Unit 1 - Trigonometry (Ch. 1)

The triangle is the most basic closed polygon. 3D images in video games and computer generated graphics revolve around the most basic of 2D shape - the triangle. In these chapters, we will explore the relationships between basic geometrical shapes. We will apply our understanding of angles and side-lengths to solve problems.

 As usual, this outline is subject to change without notice. Attend class for the most up-to-date version.
