Chapter 13: Geometric Applications of Trigonometry

In this chapter, we showcase how the the tools we've developed in Chapters 11 and 12 can be applied to Geometry. Our first two sections focus specifically on solving oblique (non-right) Triangles.

Our first example reviews the basics of right triangle trigonometry. The reader is referred to Section B.2 for more details and practice with these concepts.
