• An animal has radial symmetry if it can be
  divided along any plane, through a central axis,
  into equal halves.
• An animal has bilateral symmetry if it can be
  divided down its length into similar right and
  left halves forming mirror images of each other.

6
Which figure has bilateral symmetry? Which has
radial symmetry?
