- 1. Trigonometry is a branch of mathematics that deals with the relationships and properties of triangles, particularly right triangles. It involves the study of angles, sides, and trigonometric functions such as sine, cosine, and tangent. Trigonometry has applications in various fields such as physics, engineering, and astronomy, where it is used to calculate distances, angles, and measurements. By understanding trigonometric concepts, one can solve complex problems involving triangles and understand the relationship between the different elements of a triangle.
