The word trigonometry comes from Greek words meaning measurement of triangles. Solving triangles is one of many aspects of trigonometry that you study today. To develop methods to solve triangles, trigonometric functions are constructed. The study of the properties of these functions and related applications form the subject matter of trigonometry. Trigonometry has applications in navigation, surveying, construction, and many other branches of science, including mathematics and physics.
