Does the Fig. 12.28 have rotational symmetry?

Solution:

We know that

Rotational symmetry is a type of symmetry where the image of a shape is exactly the same to the original shape or image after a full angle rotation or 360° rotation.

It exists when a shape is turned, and the shape is identical to the original.

The figure given does not show rotational symmetry because one part is not shaded whereas the other three parts are shaded

So the design does not show symmetry

Therefore, the figure does not have rotational symmetry.
