Pythagoras was born in Greece on the Island of Samos. He settled in Crotone in Italy, there he began to teach a few students and they were soon known as the Pythagoreans.

Pythagoras' Theorem states that for all right-angled triangles, 'The square on the hypotenuse is equal to the sum of the squares on the other two sides'. (The hypotenuse is the longest side and it's always opposite the right angle)
So for any right-angled triangle the square on the hypotenuse is equal to the sum of the squares on the other two sides.

Right angle triangle

In this triangle a^2 = b^2 + c^2 and angle A is a right angle.
Pythagoras' Theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle.

Some people say that he got the proof for the theorem from a mathematican
called Apasthamba in India when he journeyed there.
