How many squares do you see in this figure
How?
Lets Count..
5 black colored squares.
1 red colored square.
1 blue color square.
4 small green colored squares in middle.
5 large green colored squares.
Thus, a total of 5+1+1+4+5=16 squares.
how many circles do you see in this picture
How?
1 black circle in the middle(easily visible to all)
Now move a little away from the screen(16 more circles will be visible easily).
Thus, there are a total of 17 circles.
how many triangles are there in this picture
How?
Lets count…
Assuming smallest side of a triangle is 1 cms.
Number of triangles with side 1 cms: 12(1 + 5 + 5 +1)
Number of triangles with side 2 cms: 6(1 + 2(triangles facing upward), 1+2(triangles facing downward))
Number of triangles with side 3 cms: 2(1 triangle facing upward and 1 facing downwards).
Thus, total number of triangles are 20.

how many squares are in this picture
How?
Let’s assume the smallest square side is 0.5cm in length.
Now count the squares with different length :-
0.5cm : 8
1cm : 16 +2(in the middle)
2cm : 9
3cm : 4
4cm : 1

Total : 40
how many squares in this picture
Lets count…
Squares with side length equal to 1 matchstick: 9
Squares with side length equal to 2 matchsticks: 5(2+1+2)
Square with side length equal to 3 matchsticks: 1 (This is difficult to find, and easy to miss)
Square with side length equal to 4 matchsticks: 1 (Everybody knows)
So total number of squares : 16
