# On Pythagoras’ Theorem (VIDEO!)

Pythagoras’s Theorem states that if one draws squares on the sides of a right triangle, the largest square has area the sum of the two smaller square areas. This means it must be possible to split the large square into two rectangles, each having area matching the area of a smaller square.

In this video I show you how to do this swiftly and easily. It’s a charming little tidbit. (And then … Who says you have to stick with squares???)

Written for educators - and their students too! - this website, slowly growing, takes all the content Tanton has developed in his books, videos, and workshops, and organizes it into short, self-contained, and complete, curriculum units proving that mathematics, at all points of the school curriculum, can be joyous, fresh, innovative, rich, deep-thinking, and devoid of any rote doing! Let's teach generations of students to be self-reliant thinkers, willing to flail and to use their common sense to "nut their way" through challenges, to assess and judge results, and to adjust actions to find success. (Great life skills!)
