No, they are made of ratios (one divided by another). The ratios describe the proportions--they have only to do with the shape, and not the overall size. That is what makes them useful. If I know that two things (a "model" and "the actual thing") are in the same proportions, then I can use the model to deduce properrties of the actual thing.

False
The trigonometric functions are found by the division of two sides of a right triangle.
sine = opposite/hypotenuse
cosine = adjacent/hypotenuse
tangent = opposite/adjacent
cosecant = hypotenuse/opposite
secant = hypotenuse/adjacent
cotangent = adjacent/opposite

False.
There are more than 1 Trigonometric Funtion for different purposes.
Sine Rule, Cosine Rule, etc

Na. 3 trig functions namely sine, cosine and tangent.
Sine=opposite side to the angle/hypotenuse(longest side)
Cosine=adjacent side to the angle/hypotenuse
Tan=opposite/hypotenuse
Any derivation can be freestyled from here

False, not addition.
sine= opposite/hypotenuse
cosine=adjacent/hypotenuse
tan=opposite/adjacent

SOH-CAH-TOA
sine = opp/hyp
cosine = adj/hyp
tangent = opp/adj
It's a nice way to remember them.
