Lesson Plan: Right Triangle Altitude Theorem Mathematics • Second Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the right triangle altitude theorem, also known as the Euclidean theorem, to find a missing length.
Objectives
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.
Prerequisites
Students should already be familiar with
- the Pythagorean theorem,
- similar triangles.
Exclusions
Students will not cover
- trigonometry.
