Start by teaching the basic properties of different triangles because trigonometry is the science of triangles.
Colleges offer multiple semester-long classes in trigonometry; it's not something we can teach you in a few paragraphs on a website. If you're really interested, I recommend you take a class at a community college.

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.
Anyone who knows more trigonometry than you and is able to convey that information effectively. A person with loads of qualifications does not necessarily make a teacher.

It is important to me because I am a mathematics tutor and I would not be able to do my job if I cold not teach my pupils a part of their syllabus.
I am a retired math/science teacher. I used trig every day to teach students.

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.

It is a number - in trigonometry or elsewhere.
