## Unit 1 - Trigonometry & Triangles

Triangles are the most basic closed polygon. 3D images in computer generated graphics revolve around the most basic of 2D shape - the triangle. In this chapter, we will apply our understanding of angles and side-lengths to solve problems, specifically with triangles. ### 1.1 - Labeling Triangles & SOH CAH TOA
