### How are radial symmetry and symmetry different?

Radial symmetry is a particular kind of symmetry in which an object takes on a similar form in any direction outward from the center (like a circle, which is the most perfect radially symmetrical form). Another form of symmetry is bilateral symmetry, meaning that is a two sided symmetry, in which a left side resembles a right side; this is the kind that human bodies have. In comparison, starfish have radial symmetry.
