Lesson Plan: The Tangent Ratio Mathematics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find missing lengths and angles in a triangle using the tangent ratios.
Objectives
Students will be able to
- use right triangles to find tangent ratios,
- use special right triangles to find the tangent ratios for , , and ,
- use the tangent ratio to find missing lengths in right triangles,
- use the inverse tangent ratio to find missing angle measures in right triangles,
- solve more complex problems, such as using the tangent ratio or inverse tangent ratio in combination with the Pythagorean theorem, simple 2D shape properties, or coordinate geometry.
Prerequisites
Students should already be familiar with
- right triangles,
- the Pythagorean theorem,
- simple 2D shape properties,
- coordinate geometry.
Exclusions
Students will not cover
- non-right triangles,
- the graph of the tangent function,
- the cotangent ratio.
