Century Dictionary and Cyclopedia
• symmetrical Well-proportioned in its parts; having its parts in due proportion as to dimensions; harmonious: as, a symmetrical building; his form was very symmetrical.
• symmetrical Composed of two parts whose geometrical relations to one another are those of a body and its image in a plane mirror, every element of form having a corresponding element upon the opposite side of a median or symmetral plane, upon one continued perpendicular to that plane and at the same distance from it: said also of each part relatively to the corresponding part: as, the right arm is symmetrical with the left.
• symmetrical In a weakened sense, in zoology, having similar parts in reversed repetition on the two sides of a median plane, or meson, through an axis of the body, generally the longitudinal. Not all the parts need so correspond, nor need those which do correspond be equal.
• symmetrical Composed of parts or determined by elements similarly related to one another, and either having no determinate order (as the three lines which by their junction form a summit of a cube) or else in regular cyclical order: said also of the parts in their mutual relation.
• symmetrical Specifically, in botany, of flowers, numerically regular; having the number of members the same in all the cycles or series of organs—that is, of sepals, petals, stamens, and carpels: same as isomerous, except that in a symmetrical flower there may be more than one set of the same kind of organs. Compare regular, a., 7.
• symmetrical In organic chemistry, noting compounds which contain atoms or groups at equal relative intervals in the molecule: thus, for example, chlorobenzene, which has the formula and ethylene chlorid, ClCH2.CH2C1, are both symmetrical compounds.
