Lesson: Right Triangle Trigonometry: Solving for an Angle Mathematics • 11th Grade

In this lesson, we will learn how to find a missing angle in a right triangle using the appropriate inverse trigonometric function given two side lengths.

Lesson Plan

Students will be able to

find an unknown angle measure in a right triangle (given a figure) using the sine, cosine, and tangent ratios, and their inverse functions,
draw a figure from a question and determine an unknown angle in a right triangle,
interpret and solve real-life and applied problems using right triangle trigonometry.
