Here you'll learn how to use the Pythagorean Theorem, which states that given a right triangle with legs of lengths a and b and a hypotenuse of length c, a^2+b^2=c^2. You'll also learn the theorem's converse and what a Pythagorean Triple is.

This video provides the student with a walkthrough on using the Pythagorean Theorem.
