The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.

Pythagoras's' theorem or "got an want" on a right angled triangle but use sine rule on a non right angled triangle !! ..

The ratio of the side of a right-angled triangle opposite to a specified angle to the hypotenuse; when expressed as a real number between 0 and 1 it defines the sine of the angle

For a right angle triangle the trigonometrical ration is: tangent = opposite/adjacent
