The arrangement of body parts around a point or axis is called an animal's symmetry.
Animals with radial symmetry have a body pattern in which one cut from the top, in any direction, results in equal halves.

Bilateral symmetry is a body pattern in which equal halves can only be obtained by a cut down the midline.
• These animals tend to exhibit cephalization, which is the concentration of sense structures in the head.
