Pythagoras is often referred to as the first pure mathematician. He was born on the island of Samos, Greece in 569 BC.

General Information

Pythagoras was well educated, and he played the lyre throughout his lifetime, knew poetry and recited Homer. He was interested in mathematics, philosophy, astronomy and music, and was greatly influenced by Pherekydes (philosophy), Thales (mathematics and astronomy) and Anaximander (philosophy, geometry).

Pythagoras Theorem

Years ago, a man named Pythagoras found an amazing fact about triangles: If the triangle had a right angle (90°) and you made a square on each of the three sides, then the biggest square had the exact same area as the other two squares put together!

It is called "Pythagoras' Theorem" and can be written in one short equation: a2 + b2 = c2
Note:
1. c is the longest side of the triangle
2. a and b are the other two sides
Why Is This Useful?
If we know the lengths of two sides of a right angled triangle, we can find the length of the third side. (But remember it only works on right angled triangles!)

How Do I Use it?
Write it down as an equation:

abc triangle a2 + b2 = c2

Example: Solve this triangle.
right angled triangle

a2 + b2 = c2
52 + 122 = c2
25 +...
