Question

Does the following diagram has rotational symmetry? If yes, find the order of rotation.

Answer 1

After rotating the given image by ${90}^{\circ },$ we get the following :

We can see that whenever the image rotates by ${90}^{\circ },$ 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.
