Trigonometry - Wikipedia
Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

Trigonometry in the modern sense began with the Greeks. Hipparchus (c. 190–120 bce) was the first to construct a table of values for a trigonometric function.He considered every triangle—planar or spherical—as being inscribed in a circle, so that each side becomes a chord (that is, a straight line that connects two points on a curve or surface, as shown by the inscribed triangle ABC in ...
Trigonometry is the branch of mathematics that deals with the study of: angles triangles (tri-angles means $3$ angles) lateral and angular relationships of planar and three-dimensional figures Literally, it is from the Greek word, trigon-metron trigon means triangle metron means measurement. An Angle is the intersection of two lines. We can measure angles in:
