Overview

Learn why the Pythagorean theorem works for finding side lengths of right triangles. This video focuses on modeling what the Pythagorean theorem actually means and why it will find the missing side of a right triangle. This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers.
