A unit of angular measurement where the angle is measured by the length of the arc divided by the radius.
Angles that share the same terminal side but differ by whole rotations.
An angle measured counterclockwise from the initial side.
An angle measured clockwise from the initial side.
An angle positioned with its vertex at the origin and its initial side on the positive x-axis.
The starting position of an angle's ray in standard position.
The position of an angle's ray after rotation.
A complete 360-degree or 2π radian turn.
The acute angle formed by the terminal side of an angle and the x-axis.
