Geometry Module 2, Topic E, Overview

Happy Students

Students link their understanding of similarity and relationships within similar right triangles formally to trigonometry.  In addition to the terms sine, cosine, and tangent, students study the relationship between sine and cosine, how to prove the Pythagorean Theorem using trigonometry, and how to apply the trigonometric ratios to solve right triangle problems.
