## Simple Explanation of Pythagoras' Theorem

In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

## Pythagoras' Theorem

2000 years ago, mathematician, Pythagoras discovered a rule connecting the side lengths of right-angled triangles:

"

This is called Pythagoras' Theorem, and it is true for all triangles with a right-angle. It can be written in one short equation:

"

*When the triangle has a right angle*(90°)*and squares are made on each of the three sides, then**the biggest square has the exact same area as the other two squares put together!"*This is called Pythagoras' Theorem, and it is true for all triangles with a right-angle. It can be written in one short equation:

**a²+b²=c²****c**is the**longest side**of the triangle**a**and**b**are the other two sides
