Share. By Jennifer Kennedy. Definition: Radial symmetry is the regular arrangement of body parts around a central axis. When an organism is radially symmetrical, you could cut from one side of the organism through the center, to the other side, anywhere on the organism, and this cut would produce two equal halves.Examples: Sea urchins have radial symmetry.hen an organism is radially symmetrical, you could cut from one side of the organism through the center, to the other side, anywhere on the organism, and this cut would produce two equal halves.
Formally the rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space. Rotations are direct isometries, i.e., isometries preserving orientation. Therefore a symmetry group of rotational symmetry is a subgroup of E + (m) (see Euclidean group). Symmetry with respect to all rotations about all points implies translational symmetry with respect to all translations, so space is homogeneous, and the symmetry group is the whole E (m).
