arrows going both way left and right

If a figure has a rotation symmetry, then the figure will look exactly the same after rotation.

The figures with rotation symmetry are:

  • a cross-like shape where all each arm is a shape of an arrow that are identical
  • arrows going both way left and right

I've added an image to illustrate the rotation of each figure.

From the attachment, we have the following observations

  • When the heart and the right-angled triangle are rotated, the new figures do not return to their original form
  • However, when the cross like shape and the arrow are rotated, the new figure looks exactly like the original figure.

Hence, (b) and (d) have rotation symmetry.
