The Pythagorean Theorem The most important theorem in the universe! Really. I am not kidding

Although used long before Pythagoras was born, he is attributed with the first proof that it is always true.

Here’s his proof So what the heck does that mean?

He explained it this way The square of the hypotenuse of a right triangle is equal to the sum of the squares of the two legs.

Let’s try it!

Pythagorean Theorem (Maybe sung to the tune of “Gilligan’s Isle”) Pythagoras was born a Greek Upon the Samos Isle. He grew to read and write and speak With a philosophic style The square of the hypotenuse Of a right triangle Is equal to the sum of the squares Of the two adjacent sides Let’s Sing © Susan Gossling all rights reserved

He was a mighty thinking man And traveled all around He formed a school and taught them That reality is math The square of the hypotenuse Of a right triangle Is equal to the sum of the squares Of the two adjacent sides The weather started getting rough The Crotons drove them out Pythagoras he later died In B.C. 480 about The square of the hypotenuse Of a right triangle Is equal to the sum of the squares Of the two adjacent sides
