Pythagoras theorem is an elegantly simple relationship between the side lengths of right angled triangles. It involves the operation of squaring, multiplying a number by itself to find its square and the inverse of that, finding square roots.

Take the example of a square with side lengths of 5 units (e.g. cm, m, km).

5 squared is 25 (5 x 5).

This is written as 52 = 25.

25 square units (e.g. cm2, m2, km2 ) is the area of the square.
