From Greek: tri = threegon = corner metry = measurement.
plane trigonometry spherical trigonometry
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
Hipparchus is the father of trigonometry.
Trigonometry based on a unit circle and radians and trigonometry based on a right triangle.
"Trigonometry" comes from the Greek words trigonon and metron, and roughly translates to "the measurement of angles".
Algebra and trigonometry

Trigonometry. The term "trigonometry" has origins in Latin, as it comes from the Latin word "trigonometer", which means "triangle measure".

Yes in some educational establishments geometry which means earth or land measurements is followed by trigonometry which means triangular measurements and both subjects are allied to each other.
It is a number - in trigonometry or elsewhere.
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.
