To answer this question, first we should know about biological symmetry. Biological symmetry can be seen as a balanced distribution of copy parts or shapes in an organism's body. The biological symmetry is called the balanced distribution of the body shapes. Biological symmetry can be classified into several types: radial symmetry, bilateral symmetry, spherical symmetry, biradial symmetry and asymmetry. While sponges and placozoans consider two groups of animals that show no symmetry (i.e. asymmetric), some form of symmetry exhibits, and is defined by, the body plans of most multicellular organisms. There are now only a few kinds of symmetry in body planes that are possible.

Bilateral symmetry | Radial symmetry |

Bilateral symmetry produces only two sides along its sagittal plane as left and right | Radial symmetry produces halves of the same body around the central axis. |

Sagittal plane splits the body into the right and left sides | Could not split the body into left and right sides |

Analogous body parts are arranged equally on both the right and the left sides | Analogous body parts are organized around the central axis in a regular fashion. |
