There are two triangles in front of you. The top one is completely divided into four fragments, painted in different colors. In the lower triangle, the same fragments are arranged in a different order. Attention, question. Where did the extra empty square come from? The answer is within.
In reality, this is not an optical illusion, but an interesting problem. The areas of the shaded figures are, of course, equal to each other (32 cells), however, what is visually observed as 13×5 triangles, in fact, is not such, and has different areas (S13×5 = 32.5 cells). That is, the error disguised in the problem statement is that the initial figure is called a triangle (in fact, it is a concave 4-gon). This is clearly visible in the diagram below - the “hypotenuses” of the upper and lower figures pass through different points: (8.3) at the top and (5.2) at the bottom. The secret is in the properties of the blue and red triangles. This is easy to check with calculations.
The ratios of the lengths of the corresponding sides of the blue and red triangles are not equal to each other (2/3 and 5/8), therefore these triangles are not similar, and therefore have different angles at the corresponding vertices. Let's call the first figure, which is a concave quadrilateral, and the second figure, which is a concave octagon, pseudotriangles. If the bottom sides of these pseudo-triangles are parallel, then the hypotenuses in both 13x5 pseudo-triangles are actually broken lines (the top picture creates a bend inward, the bottom one creates an outward bend). If you superimpose the upper and lower 13×5 figures on top of each other, then between their “hypotenuses” a parallelogram is formed, which contains the “extra” area. In the diagram, this parallelogram is shown in the correct proportions.
The acute angle in this parallelogram is equal to arcctg 46 ≈ 0°1′18.2″. The minute hand on a working watch moves to this angle in 12.45 seconds. It is by this amount that the obtuse angle in the parallelogram under consideration differs from the straight angle. Visually, such an insignificant difference is not noticeable, but it is clearly visible in the animation.
According to Martin Gardner, this task was invented by New York amateur magician Paul Curry in 1953. However, the principle behind it was known as early as the 1860s. You can notice that the lengths of the sides of the figures from this problem (2, 3, 5, 8, 13) are consecutive Fibonacci numbers.

Let's take a book with a ball -
Let's call them bodies.
And let's draw the figures -
Circle with an oval and a ray.
Let's continue drawing
Rhombus, segment and square.
Did you guess it or not?
Geometry secret?
Drawn drawing
Can tell a lot
The main thing to remember is
And the secret to understand it:
The body can be voluminous
Round or three-sided.
You can take the body in your hands,
And the figures - to draw
Can we, or draw
And place it on a plane.
How many are there in this world?
Amazing secrets.
We all want to know
To know the world of wisdom.

And my brother, Seryozha,
Mathematician and draftsman -
On Baba Shura's table
Draws all sorts of ___
(Shapes)
***
It looks like a wheel
In the middle is the letter O
Rolling along the road
And hides in a daisy
His temper is not cool at all
Did you guess it? This - ____
(Circle)
Dot
Let our courtyard be gloomy outside the window today.
I took a felt-tip pen and pencil and decided to draw shapes.
There is a sheet of paper in front of me, how white and clean it is.
Use a felt-tip pen to poke it in the middle of the leaf.
And a dot appears on the sheet.
Line
Even if there are a lot of points, I lead the way through them.
Connecting point to point, I drew a line path.
The path, bending and winding, the path is called a line.
Straight line
My mother advised me to lead my path straight.
How to make a line straight - it just doesn’t work.
Is my felt-tip pen lame or is my hand getting confused?
But with a ruler it’s so easy to draw a line on a sheet.
Look how smooth it is, this line is straight.
Angle (acute, straight, obtuse)
My mother took the piece of paper and folded the corner.
An angle like this in adults is called a right angle.
If the angle is narrower, it is acute; if it is wider, then it is obtuse.
***
I’m sharp - I want to draw, now I’ll take it and draw it.
I lead from a point two straight lines, as if two rays,
And we see an acute angle, like the tip of a sword.
And for an obtuse angle we repeat everything again:
We draw two straight lines from the point, but we will separate them wider.
Look at my drawing, it’s like scissors inside,
If we take it by two rings, we will expand it to the end.
Triangle
The plane flies across the sky, delta wing,
My bike has a triangular saddle
There is such an object - a square, and all this is a triangle.
Then mom put three matches on the table
And she made me a triangle out of matches.
And at this time I was drawing and watching my mother,
I connected three straight lines and did the same.
***
You and I will build a house,
The roof will be a triangle,
The roof has sharp corners,
How many are there? One two Three!
Square
My older brother came home from school and made a square out of matches.
My mother gave me chocolate, I broke off a piece - a square.
And the table is a square, and the chair is a square, and on the wall the poster is a square.
A board where chess stands, and each cell is a square,
There are horses and elephants and fighting figures standing there.
***
Here are the four sides
And they are always equal.
And that figure, guys,
It's called a square.
Circle and Circle
My brother and I live together, we have so much fun together,
We will place a mug on a sheet of paper and trace it with a pencil.
The result is what you need - it’s called a circle.
My brother considers himself a master in drawing,
He painted over everything inside the circle with a felt-tip pen.
Here is a red circle, a circle, with a blue rim around the edge.
circle - plate, wheel, circle - hoop, belt.
circle - the outline of a circle. I look at our piece of paper
I began to look for the corner of the circle, but could not find it.
Brother laughs - that's it! Yes, a circle has no angle,
You won’t find corners on a plate or a coin; they don’t exist.
***
Let's draw a circle:
There is a mouth and a couple of dots in it.
The sun is round and the ball,
The circle has been familiar to us for a long time, that is.
Trapezoid
Trapezoid, trapezoid, there is such a figure,
But I don't know her. Where do you live, trapezoid,
In America, in China? Maybe behind the trapeze
Should you go to Greece? Mom says: No need
Trapeze is next to you. I will dispel your melancholy
Wait a minute. And on the ironing board
Lays down the skirt, runs the iron over it,
So as not to puff up like a bag:
- Here's a trapeze, you shouldn't go to Greece.
Oval
How to draw an oval? I called my brother for help.
My brother took a felt-tip pen and skillfully drew an oval for me:
You slightly flatten the circle, it turns out to be an oval.
How many times have I seen it, the mirror in the bathroom is an oval!
The oval is both a dish and an egg. Mom says: Face
Yours is oval. Let it be oval
As long as it's not sad. We laughed in the oval
A face was drawn. Oval - elongated circle
And her face is surprised.
***
There's an oval hanging on the wall,
I saw myself in it.
I love looking in the mirror
I like to twirl in front of him
Cube
The postman brought us a box - a package for me and my brother.
The box is a cube, it has six sides, all sides are squares.
What's in the package? There are shavings and sawdust,
Sweets and bagels, also jars with jam.
Cylinder
-Cylinder, what is it? - I asked my dad.
The father laughed: - A top hat, it's a hat.
To have a correct idea,
A cylinder, let's say, is a tin can.
The steamer's pipe is a cylinder, the pipe on our roof is the same,
All pipes are similar to a cylinder. And I gave an example like this -
My favorite kaleidoscope, you can’t take your eyes off it,
And it also looks like a cylinder.
Cone
Mom said: - And now
My story will be about the cone.
Stargazer in a high hat
Counts the stars all year round.
Cone - stargazer's hat.
That's what he is like. Understood? That's it.
Mom was standing at the table
I poured oil into bottles.
- Where is the funnel? No funnel.
Look for it. Don't stand on the sidelines.
-Mom, I won’t budge.
Tell us more about the cone.
-The funnel is in the form of a watering can cone.
Come on, find her for me quickly.
I couldn't find the funnel
But mom made a bag,
I wrapped the cardboard around my finger
And she deftly secured it with a paper clip.
The oil is flowing, mom is happy,
The cone came out just right.
Pyramid
I saw the picture. In this picture
There is a pyramid in the sandy desert.
Everything in the pyramid is extraordinary,
There is some kind of mystery and mystery in it.
And the Spasskaya Tower on Red Square
It is very familiar to both children and adults.
Look at the tower, it looks ordinary,
What's on top of it? Pyramid!
Ball
Hit! Hit! Another blow!
A ball flies into the goal - a ball!
And this is a green watermelon ball, round, delicious.
Take a better look - what a ball! It is made of nothing but circles.
Cut the watermelon into circles and taste them.
Figure painting
Holding scissors like a sword
I decided to create a picture,
Multi-colored paper
I cut like a web.
And in the corner of the album sheet
I'm gluing a square at home.
The path runs like a ribbon...
From a square window
Seen from the forest edge
Go to your feeder
Without fear, animals can:
At the rectangular door
Food for them is left in a niche,
Eat boldly, just quietly:
There on the triangular roof
With your ringing song
The nightingale has perched.
The clouds are above him, and above,
Lighting up everything around
The circle of the sun is golden!
So as not to bother in winter
For those who will live in the house
I really need a garden -
Fruits vegetables. And so:
Finely cut strips -
There will be boards for the fence,
And behind them for order
There will be an earthen bed.
Hey, who's in the house? Do not snooze!
Harvest!
Two circles - two watermelons,
Three ovals - corn
And a circle of huge turnips,
To pull out, you need a friend,
I glued it very tightly -
This is a fabulous turnip.
Where is parents? Look!
What did I do, appreciate it!
Mom and dad praise their son
His painting was a success!

There are also three sides to it:
One, two, three - just look.
We draw a triangle
Now we will know him.
The plane flies across the sky
delta wing,
On my bike
Triangular saddle,
There is such an object - a square,
And all this is a TRIANGLE.
Here mom has three matches
I put it on the table
And a triangle for me
Made it out of matches.
And at this time I was drawing
And I watched my mother
I connected three straight lines
And he did the same.
I'm under the triangular roof
I'll hide from the rain.
The roof is triangular,
Hide me quickly!
Rectangle
Like a rectangle window
Neat, like a schoolboy.
It looks like a door, like books,
And on the boy’s backpack.
On the bus, on the notebook,
For a big chocolate bar.
At the pig trough
And for a child's candy wrapper.
My canvas is not square
It's rectangular!
I'll draw on it
Various shapes!
We stretched the square
And presented at a glance,
Who did he look like?
Or something very similar?
Not a brick, not a triangle -
The square became a rectangle.
The mountains are similar to it.
It’s also similar to a children’s slide.
And also on the roof of the house
He looks very similar.
What did I wish for?
It's a triangle, friends.
These figures are rushing around the city,
Children are taken to kindergartens and schools.
There is a bus, a trolleybus, a tram.
Keep an eye on the road and don't yawn!
The houses look like this figure.
What am I writing about? Answer, friends!
Rhombus
A kite is not an easy one!
The snake, it's in the shape of a diamond!
He flies above the ground
Even higher than the house.
The elephant turned the square
He looked closer and sighed.
He sat down on top, crushed it a little,
And the square became a diamond!
A rhombus is a complex figure,
It combines two:
Triangle one and two -
The figure suddenly became alone.
There are four sides to a rhombus.
They are equal to each other.
Four in a rhombus and corners,
Two are equal to each other.
(Mazhirina N.)
Slightly flattened square
Invites you to identify:
Acute and obtuse angles
Eternally bound by fate.
Have you guessed what it's all about?
What should we call the figure?
Polygon
Six obtuse angles inside
Look at the figure
And imagine that from a square
We got his brother.
There are too many angles here
Are you ready to name him?
Trapezoid
If you climb higher with a saw,
Cut off the roof of the house,
Then we will offend the owners,
But we'll see the trapeze!
And then we'll fix everything
And we’ll take the skirt out of the closet.
We'll see: the skirt too
It looks like a trapezoid!
The triangle has been filed
And we got the figure:
Two obtuse angles inside
And two spicy ones - look.
Not a square, not a triangle,
And it looks like a polygon.
There is such a figure
But I don't know her.
Where do you live, trapezoid,
In America, in China?
Maybe behind the trapeze
Should you go to Greece?
Mom says: - No need.
Trapeze is next to you.
I will dispel your melancholy
Wait a minute.
And on the ironing board
Lays out the skirt
He runs an iron over it,
So as not to puff up like a bag:
- Here's a TRAPEZE for you,
You shouldn't go to Greece.
Cone
Inverted cone -
A vase for flowers.
I'll fill it with water,
And the bouquet is ready!
Mom said: - And now
My story will be about the cone.
Stargazer in a high hat
Counts the stars all year round.
CONE - stargazer's hat.
That's what he is like. Understood? That's it.
Mom was standing at the table
I poured oil into bottles.
- Where is the funnel? No funnel.
Look for it. Don't stand on the sidelines.
- Mom, I won’t budge.
Tell us more about the cone.
- The funnel is in the form of a watering can cone.
Come on, find her for me quickly.
I couldn't find the funnel
But mom made a bag,
I wrapped the cardboard around my finger
And she deftly secured it with a paper clip.
The oil is flowing, mom is happy,
The cone came out just right.
Cylinder
Cylinder, what is it? - I asked my dad.
The father laughed: - A top hat, it's a hat.
To have a correct idea,
A cylinder, let's say, is a tin can.
Steamboat pipe - cylinder,
The pipe on our roof too,
All pipes are similar to a cylinder.
And I gave an example like this -
My beloved kaleidoscope,
You can't take your eyes off him,
And it also looks like a cylinder.
I remember all the figures
A telescope will help!
She is a top hat, for example!
And by the way! There is a circle in it too!
Ball
If the circle is three-dimensional,
So it's a ball!
Fishes! Lunch hour
It's time in the aquarium!
Hit! Hit! Another blow!
The ball flies into the goal - BALL!
And this is a watermelon ball
Green, round, tasty.
Take a better look - what a ball!
It is made of nothing but circles.
Cut the watermelon into circles
And taste them.
How can we not turn him around?
There are exactly six equal faces.
We can play lotto with him,
Let's just be careful:
He is neither affectionate nor rude
Because it's a cube.
I'll show you the cube!
That's how huge it is!
With smooth edges!
He is equilateral!
The postman brought us a box -
A parcel for me and my brother.
The box is a CUBE, it has six sides,
All sides are squares.
What's in the package?
There are shavings and sawdust,
Candies and bagels,
More jars of jam.
Pyramid
The Egyptians put them together
And they crafted it so cleverly,
That they stand for centuries.
Guess for yourself, children.
What kind of bodies are these?
Where is the top visible to everyone?
Did you guess it? Because of the view
Everyone knows the pyramid.
I saw the picture. In this picture
There is a PYRAMID in the sandy desert.
Everything in the pyramid is extraordinary,
There is some kind of mystery and mystery in it.
And the Spasskaya Tower on Red Square
It is very familiar to both children and adults.
Look at the tower, it looks ordinary,
What's on top of it? Pyramid!
