plane trigonometry spherical trigonometry
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
Plane trigonometry is trigonometry carried out in (on) a plane. This could be contrasted with spherical trigonometry, which is trigonometry carried out on the surface of a sphere. Certainly there are some other more complex forms of trig.
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
Hipparchus is the father of trigonometry.
TRIGONOMETRY
Trigonometry is the study involving the measurements of the lengths of sides and the angles of triangles (or trigons)..
An identity is like an equation which is true for all values of the variable.
