Angles
An angle is an amount of rotation of a half-line (or ray) in a plane about its end point from an initial position to a terminal position. The important terms are: Measurement of angle, Positive and Negative angles, Lines at..

The angles (2 p + A), (4 p + A)......have the same initial and terminal arm as the angle A and so these angles are called co-terminal angles . For all such angles, the value of any trigonometric ratio is the same. Thus, ..
