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.
