If any object rotates and there is no change in the shape and size, then it is said to have rotational symmetry. In this section we will learn more about rotational symmetry.
Lines_of_symmetry_for_regular_polygons
The concept of line symmetry is closely related to mirror reflection. A shape has line symmetry when one half of it is the mirror image of the other half. A mirror line, thus, helps to visualise a line of symmetry.
