Lesson Plan: Angles of Elevation and Depression Mathematics • 11th Grade
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 using the tangent ratio.
Students will be able to
- recognize which angle represents an angle of depression and which angle represents 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, namely, the tangent ratio, to solve problems involving one or more angles of elevation.
Students should already be familiar with
- how to describe directions using a combination of angles and north, south, east, and west,
- right triangle trigonometry to find unknown angle measures and side lengths.
Students will not cover
- questions that use radians,
- problems that require the use of the laws of sines or cosines.
