Trigonometry is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees (right triangles). Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships.

Trigonometry has applications in both pure mathematics and in applied mathematics, where it is essential in many branches of science and technology. It is usually taught in secondary schools either as a separate course or as part of a precalculus
course.
Trigonometry has a wide range of practical applications
in fields such as engineering, physics, astronomy, navigation,
architecture, and surveying. In engineering, trigonometry is used for
calculating distances, measuring angles, and designing structures. In
physics, trigonometry is applicable in studying motion, waves, optics, and
mechanics.
Astronomy also relies on trigonometry for determining
distances, calculating positions, and estimating sizes. Navigation uses
trigonometry for determining location and navigating ships and aircraft.
Architecture involves designing buildings, calculating angles, and
determining dimensions, all of which require the use of trigonometry.
Surveying uses trigonometry to measure distances and angles, as well
as determining elevations. In addition to its practical applications,
trigonometry also improves mathematical skills such as geometry, algebra,
and calculus.
