Angular displacement of a body is theangle through which it has been rotated about a fixed axis. It is measured in radians. Angular velocity of a body is the rate of change ofangular displacement over a period of time.

Angular displacement is defined as “the angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis”. It is the angle of the movement of a body in a circular path.
It is the angle made by a body while moving in a circular path. Before we go any further into the topic, we have to understand what is meant by rotational motion. When a rigid body is rotating about its own axis, motion ceases to become a particle. It is so because in a circular path velocity and acceleration can change at any time. The rotation of rigid bodies or bodies which will remain constant throughout the duration of rotation, over a fixed axis is called rotational motion.
The angle made by the body from its point of rest at any point in the rotational motion is the angular displacement.
For example- If a dancer dancing around a pole does one full rotation, his or her angular rotation will be 360 degree. On the other hand, he or she makes half a rotation; the displacement will be 180 degree.
