Angle of Rotation

Angle of Rotation is explained.

 

(1)The action of rotation about an axis or centre is called rotation.

Eg:-movement of hands of clock

(2)Rotation, like movement of the hands of a clock, is called a clockwise rotation; otherwise it is called anticlockwise.

(3)The centre of rotation is a fixed point around which an object rotates.

(4)The angle of turning during rotation is called the angle of rotation.

A full turn means a rotation of 360o.

(5)Every object has a rotational symmetry of order 1, as it occupies same position after a rotation of 360 o.
