# MATH041 - Trigonometry - Triangulation

Triangulation is the process used to determine the location of a distant point by measuring the observed angles of the line-of-sight to that point from two different locations. In other words, given one side of a triangle, and two angles, one can determine the lengths of the other sides. Triangulation has many applications from radar to motion capture, but was initially used for surveying.

By covering the topic of triangulation, this course will introduce many of the concepts of trigonometry, the study of triangles and trigonometric functions.
