### What did Pythagoras discover?

He discovered how to find the length of the missing side of a right triangle, so if there was a 5 cm line and a 4 cm line he could tell the length of the other line on a triangle. The answer to the 5 cm by 4 cm would be 3 cm. That is his famous 5, 4, 3 triangle. The formula for it is A squared plus B squared equals C squared.
