TRIGONOMETRY
Hipparchus is the father of trigonometry.
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
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 based on a unit circle and radians and trigonometry based on a right triangle.
