TRIANGLE TRIGONOMETRY
In any triangle the three sides a, b, c and the three angles A, B, C are called the elements of the triangle. In a triangle ABC, the side BC, opposite to angle A, is denoted by ‘a’. The side CA, opposite to angle B, is denoted by b and the side AB by […]

The branch of mathematics dealing with the relationships between the angles and the sides of triangles, and the calculations based on them. It originated as the study of certain mathematical relations in a triangle containing a right angle (90°). Literally, it means triangle measurement, though its applications extend far beyond geometry. It emerged as a […]
