They may be defined as the ratios of the lengths of sides of a right angled triangle, relative to either of the other angles.sine = opposite/hypotenuse
cosine = adjacent/hypotenuse
tangent = opposite/adjacent
cosecant = hypotenuse/opposite
secant = hypotenuse/adjacent
cotangent = adjacent/opposite.

Sine and cosine.
The property of similar triangles that facilitates the development of trigonometric ratios is the concept of proportionality in corresponding sides. In similar triangles, the ratios of the lengths of corresponding sides are equal, which allows us to define sine, cosine, and tangent for any angle in a right triangle. These ratios remain consistent regardless of the size of the triangle, enabling the extension of trigonometric functions beyond right triangles to any angle in the unit circle. This relationship provides a foundational basis for trigonometry.
When finding missing side lengths in a right triangle using trigonometric functions, you typically apply ratios like sine, cosine, or tangent, which relate the angles to the lengths of the sides. Conversely, when calculating missing angle measures, you use the inverse trigonometric functions (such as arcsine, arccosine, or arctangent), which take the ratios of the sides and return the corresponding angles. Thus, the key difference lies in using direct ratios for side lengths and inverse functions for angles.
There are a few ways. First, there are a multitude of trigonometric tables which list the sines and cosines of a variety of values. if you now one trigonometric value of a number, you can find all the others by hand, and you can also use a Taylor series approximation to find a fairly accurate value. (In fact, many calculators use Taylor series to find trigonometric values.)
sin, cos and tan
Six.
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.
They are different trigonometric ratios!

Sine and cosine.
Using trigonometric ratios.
No. Sines are well defined trigonometric ratios whereas "this" is not defined at all.
Complements are defined for angles, not trigonometric ratios of angles.
Yes, since it has vertices it has angles and since it has angles it has trigonometric ratios
