What do Euclid, 12-year-old Einstein, and American President James Garfield have in common? They all came up with elegant proofs for the famous Pythagorean theorem, one of the most fundamental rules of geometry and the basis for practical application...s like constructing stable buildings and triangulating GPS coordinates. Betty Fei details these three famous proofs. (05:16)[more]

This video shows how folding paper can help students learn about the Pythagorean theorem. The video can be stopped to allow students to keep pace with the folding and explanation. (03:14)

Learn how using the Pythagorean theorem can help people solve real-world problems involving distances in this Math Shorts video. This video was made for the PBS LearningMedia library, thanks to a generous grant from the Corporation for Public Broadca...sting. It was produced in collaboration with Utah Education Network.

Este video explica el teorema de Pitágoras, a la misma vez proporcionando imágenes de la teoría. El profesor diagrama el triángulo y enseña vocabulario del teorema (el hipotenusa y los catetos). Perfecto para una introdución al tema. (10:52)

Pitágoras de Samos fue un filósofo y matemático griego. Es famoso sobre todo por el Teorema, que en realidad pertenece a la escuela pitagórica. El Teorema de Pitágoras te ayudará a resolver problemas del día a día. (2:10)

An interactive that will help students understand how to use the Pythagorean Theorem to determine the length of the slant height and altitude of a pyramid.
