Lesson: Right Triangle Altitude Theorem Mathematics • 11th Grade

In this lesson, we will learn how to use the right triangle altitude theorem, also known as the Euclidean theorem, to find a missing length.

Lesson Plan

Students will be able to

recall and use the Euclidean theorem to find missing lengths of a right triangle,
recall and use the corollary relating the altitude to the hypotenuse to find missing lengths of a right triangle,
use the Euclidean theorem in conjunction with the Pythagorean theorem to find missing lengths of shapes.
