 for Respective symmetry
From The Collaborative International Dictionary of English v.0.48 :

  Symmetry \Sym"me*try\, n. [L. symmetria, Gr. ?; sy`n with,
     together + ? a measure: cf. F. sym['e]trie. See Syn-, and
     Meter rhythm.]
     1. A due proportion of the several parts of a body to each
        other; adaptation of the form or dimensions of the several
        parts of a thing to each other; the union and conformity
        of the members of a work to the whole.
        [1913 Webster]
     2. (Biol.) The law of likeness; similarity of structure;
        regularity in form and arrangement; orderly and similar
        distribution of parts, such that an animal may be divided
        into parts which are structurally symmetrical.
        [1913 Webster]
     Note: Bilateral symmetry, or two-sidedness, in vertebrates,
           etc., is that in which the body can be divided into
           symmetrical halves by a vertical plane passing through
           the middle; radial symmetry, as in echinoderms, is that
           in which the individual parts are arranged
           symmetrically around a central axis; serial symmetry,
           or zonal symmetry, as in earthworms, is that in which
           the segments or metameres of the body are disposed in a
           zonal manner one after the other in a longitudinal
           axis. This last is sometimes called metamerism.
           [1913 Webster]
     3. (Bot.)
        (a) Equality in the number of parts of the successive
            circles in a flower.
        (b) Likeness in the form and size of floral organs of the
            same kind; regularity.
            [1913 Webster]
     Axis of symmetry. (Geom.) See under Axis.
     Respective symmetry, that disposition of parts in which
        only the opposite sides are equal to each other.
        [1913 Webster]
