answered-by-expert Expert Answer

After rotating the given image by 90o, we get the following:
We can see that whenever the image rotates by 90o, it gives the same image.

So the image has a rotational symmetry.

Also through a complete turn, it gives the similar image 4 times, so the order of rotational symmetry is 4.
