8 steps

**Step 1: **
A square is drawn on a sheet of paper. Of course, all its angles are equal to each other.

**Step 2: **
Can you pull out one of the corners, while expanding the other two?

**Step 3: **
No, no, this does not have to stretch the paper. You need to change angles only visually.

**Step 4: **
Have you already tried? Let's see how it could be done!

**Step 5: **
You see - with the help of broken lines we visually reduced one corner, and two - increased.

**Step 6: **
This problem can also be represented in the reverse order.

**Step 7: **
Show your friends a square, drawn by broken lines (only not on a sheet in a cage). And ask them to choose the largest and smallest corners.

**Step 8: **
Or just ask if the angles are equal or not.
