Rotational symmetry:- When an object is rotated about the center by a number of degrees and the object appears to be the same. It is known as the rotational symmetry of the object.

The order of symmetry is the number of positions the object looks the same in a $360^{\circ}$ rotation.

The rotational symmetry of order more than one is: $(a),\ (b),\ (d),\ (e)$ and $(f)$ because in these figures, in a complete turn, the object looks exactly the same more than once.
