symmetry

A due proportion of the several parts of a body to each other; adaptation of the dimensions of the several parts of a thing to each other; or the union and conformity of the members of a work to the whole. Symmetry arises from the proportion which the Greeks call analogy, which is the relation of conformity of all the parts to a certain measure; as the symmetry of a building or an animal body. Uniform symmetry, in architecture, is where the same ordonnance reigns throughout the whole. Respective symmetry, is where only the opposite sides are equal to each other.
