The Formula

The Pythagorean theorem was actually used by the sumerians 2000 years prior, but it was Pythagoras who proved the theorem would always work The theorem states that in a right triangle, the sum of the squares of the two right-angle sides will always be the same as the square of the hypotenuse

Pythagoras

Reminders:

Lived in the 500 BC'sHad a near cult-like followingHe hated beansHe and his followers believed there were two ways to make order out of chaos- math and musicMusic is noise that makes sense, and mathematics is rules for how the world works.Donald Duck went over this in "Donald in Mathmagic Land"

The theorem can only be applied to right triangles

The hypotenuse is the longest side of a triangle, and the side found by the pythagorian theoremEx. 3(3)+4(4)=5(5)9+16=25
