Note: A curve or a plane figure is symmetrical with respect
to a given line, and a line, surface, or solid with
respect to a plane, when for each point on one side of
the line or plane there is a corresponding point on the
other side, so situated that the line joining the two
corresponding points is perpendicular to the line or
plane and is bisected by it. Two solids are symmetrical
when they are so situated with respect to an
intervening plane that the several points of their
surfaces thus correspond to each other in position and
distance. In analysis, an expression is symmetrical
with respect to several letters when any two of them
may change places without affecting the expression; as,
the expression a^{2}b ab^{2} a^{2}c ac^{2}
b^{2}c bc^{2}, is symmetrical with respect to the
letters a, b, c.
[1913 Webster] -- {Sym*met"ric*al*ly}, adv. --
{Sym*met"ric*al*ness}, n.
[1913 Webster]
