What Are the Sin, Cos and Tan of an Angle?

A measure of the separation between two rays which share a common starting point

The sine of an angle is defined as the length of the opposite side divided by the length of the hypotenuse.

The cosine of an angle is defined as the length of the adjacent side divided by the length of the hypotenuse.

The tangent of an angle is defined as the length of the opposite side divided by the adjacent side.

Given an acute angle in a right triangle, the opposite leg is across from the angle

Given an acute angle in a right triangle, the adjacent leg is a part of the angle

The longest side in a right triangle and the side across from the right angle
