Syllabification: Py·thag·o·re·an the·o·rem

Pronunciation: /pəˌTHaɡəˈrēən/ /pī-/

A theorem attributed to Pythagoras that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

The History

Pythagoras lived in the 500s, and was one of the first Greek mathematical philosophers. He spent most of his life in the Greece and Italy. He had a admirers who followed him around and educated others of what he had previously taught them. Both men and women were Pythagoreans. The Pythagoreans (the followers) were known for their pure souls. They grew their hair long and wore only simple clothing, and traveled barefoot.

The Formula

About two thousand years ago, there was an fascinating revelation about triangles. When a triangle has a right angle (90°) and squares are made on each of its

three sides, then the biggest square has the same area as the sum of the other two squares put together.
