The sine rule(also known as the "law of sines") is:

a/sin A = b/sin B = c/sin C

where the uppercase letters represent angles of a triangle and the lowercase letters represent the sides opposite the angles (side "a" is opposite angle "A", and so on.)

Sine Ratio(for angles of right triangles):

Sine of an angle = side opposite the angle/hypotenuse

written as

sin=opp/hyp.

How does one differentiate between the sine rule and the cosine rule?

The sine rule is a comparison of ratios: (sin A)/a = (sin B)/b = (sin C)/c. The cosine rule looks similar to the theorem of Pythagoras: c2 = a2 + b2 - 2ab cos C.

What is the ratio of side opposite over hypotenuse?

It is the Sine(Sin) ratio. Sin(angle) = o/h


What is the ratio between the opposite and hypotenuse?

The ratio between the opposite side and the hypotenuse in a right triangle is known as the sine of the angle opposite the opposite side. Mathematically, this can be expressed as ( \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} ). Therefore, for a given angle ( \theta ), this ratio is equal to the sine of that angle.
