Rotational Symmetry :

In a fixed center point, when an object exactly looks the same even when rotated in certain number of degrees, then its said to have rotational symmetry. It is also called as radial symmetry. An object can have more than one rotational symmetry. Many geometrical figures like rectangles, squares, circles, and all regular polygons has rotational symmetry.

Example :

Real time examples of Rotational symmetry are London eye, Dart board etc.,
