This study guide can be used to teach students the relationship between the sides of a 45-45-90 triangle. The lesson uses the Pythagorean Theorem to show students the shortcut relationship between the legs and hypotenuse.

This study guide is great for use with whole-class instruction or you can have students complete the lesson on their own by following along with my free online lesson. The online lesson includes a practice quiz with instant feedback!
