Answer:
Rotational symmetry is defined as the symmetry attained, when a shape is rotated and it still looks the same.
The order of rotational symmetry of a shape is given by the number of times it can rotate around a full circle and still look the same.
The minimum order of rotational symmetry a shape can have is 1.
Many shapes have rotational symmetry like- rectangles, squares, circles, and all regular polygons.
