# Lesson Plan: Angles of Elevation and Depression Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve real-world problems that involve angles of elevation and depression.

#### Objectives

Students will be able to

• recognize which angle is an angle of depression and which angle is an angle of elevation,
• sketch a diagram from a real-world problem involving an angle of elevation or depression and use this to help solve the problem,
• use right trigonometry along with the law of sines and cosines to solve problems involving one or more angles of elevation.

#### Prerequisites

Students should already be familiar with

• how to describe directions using a combination of angles and north, south, east, and west,
• using right triangle trigonometry to find unknown angle measures and side lengths,
• the law of sines and the law of cosines and how to use them to calculate unknown angle measures and side lengths.

#### Exclusions

Students will not cover

• problems that do not involve angles of elevation or depression.
