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.
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.)
Given a unit circle (radius = 1) and a counterclockwise angle (theta) between the positive x axis, with the x-y coordinate of the point on the circle that the angle intersects, the three basic trigonometric ratios are... 1. sine (theta) is y 2. cosine (theta) is x 3. tangent (theta) is x / y
Right triangle ratios serve as the foundation for defining trigonometric functions such as sine, cosine, and tangent, which relate the angles of a triangle to the lengths of its sides. The unit circle, a circle with a radius of one centered at the origin of a coordinate plane, extends these concepts by allowing trigonometric functions to be defined for all angles, not just those in right triangles. In the unit circle, the x-coordinate corresponds to the cosine of the angle, while the y-coordinate corresponds to the sine, thus linking the geometric representation of angles to their trigonometric values. This connection facilitates the understanding of periodic properties and the behavior of trigonometric functions across all quadrants.

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!

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
We take side to take trigonometric ratios according 2 the vertex of triangle which is given.
