What is rotational symmetry?
When the figure is turned about a fixed point; it is called rotation.
This rotation can be: (a) clockwise (b) anticlockwise
The fixed about which the figure is rotated is called centre of rotation.
The angle of turning during rotation is called the angle of rotation.
A quarter turn means a rotation of 90°
A half turn means a rotation of 180°
A full turn means a rotation of 360°
A figure is said to have rotational symmetry if it onto more than once during a complete rotation, i.e., 360°
