Trigonometry comes from the Greek words Tries and Gonia. Tries means three, Gonia means angle and Metron means measure. Trigonometry is a branch of mathematics that deals with the ratio between the sides and the angles of triangles and the calculations based on them. Trigonometry also deals with trigonometric functions such as sine, cosine and tangent. Trigonometry is used in surveying to determine heights and distances, in navigation to determine location and distances, and in fields like nondestructive testing for determining things such as the angle for reflection or refraction of an ultrasound wave.

Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometry is a specialized area of geometry concerned with the properties and relations among the parts of a triangle and originated as the study of certain mathematical relations in a triangle containing a right angle (90°). Trigonometry is all about measurement of the problems.
