"The Pythagorean Theorem is a powerful tool that people have used for centuries -- and at its heart is the right triangle. Join our hosts as they investigate the relationship between a right triangle's legs and the hypotenuse, uncover the history of the Pythagorean Theorem and show how it can be applied to situations in the real world. Students will see how this theorem can be used to find the length of an unknown side, be warned of a common mistake made when working with square roots and discover that the distance formula is an application of the Pythagorean Theorem on the coordinate plane."--Container.
