1
:  balanced proportions; also :  beauty of form arising from balanced proportions
2

3
:  a rigid motion of a geometric figure that determines a one-to-one mapping onto itself
4
:  the property of remaining invariant under certain changes (as of orientation in space, of the sign of the electric charge, of parity, or of the direction of time flow) —used of physical phenomena and of equations describing them

symmetry

noun    (Concise Encyclopedia)

In geometry, the property by which the sides of a figure or object reflect each other across a line (axis of symmetry) or surface; in biology, the orderly repetition of parts of an animal or plant; in chemistry, a fundamental property of orderly arrangements of atoms in molecules or crystals; in physics, a concept of balance illustrated by such fundamental laws as the third of Newton's laws of motion. Symmetry in nature underlies one of the most fundamental concepts of beauty. It connotes balance, order, and thus, to some, a type of divine principle.
