sym·me·try

 (sĭm′ĭ-trē)
n. pl. sym·me·tries
1. The correspondence of the form and arrangement of elements or parts on opposite sides of a dividing line or plane or about a center or an axis: the symmetry of a butterfly's wings.
2. A relationship in which there is correspondence or similarity between entities or parts: the symmetry of the play, which opens and ends with a speech by a female character.
3. Beauty as a result of pleasing proportions or harmonious arrangement: "Here were the ringlets, framing a face of exquisite symmetry" (Clive Barker).
4. Physics Invariance under transformation. For example, a system that is invariant under rotation has rotational symmetry.

[Latin symmetria, from Greek summetriā, from summetros, of like measure : sun-, syn- + metron, measure; see mē- in Indo-European roots.]

symmetry

(ˈsɪmɪtrɪ)
n, pl -tries
1. similarity, correspondence, or balance among systems or parts of a system
2. (Mathematics) maths an exact correspondence in position or form about a given point, line, or plane. See symmetrical2
3. beauty or harmony of form based on a proportionate arrangement of parts
4. (General Physics) physics the independence of a property with respect to direction; isotropy
[C16: from Latin symmetria, from Greek summetria proportion, from syn- + metron measure]

sym•me•try

(ˈsɪm ɪ tri)

n., pl. -tries.
1. the correspondence in size, form, and arrangement of parts on opposite sides of a plane, line, or point; regularity of form or arrangement in terms of like, reciprocal, or corresponding parts.
2. the proper or due proportion of the parts of a body or whole to one another with regard to size and form; excellence of proportion.
3. beauty based on or characterized by such excellence of proportion.
4. a type of regularity, as of a circle or other plane figure, that is characterized by the geometric operations, as rotation or reflection, that leave a figure unchanged.
5. a property of a physical system that allows the system to remain unchanged by a specific physical or mathematical transformation, as rotation or translation.
[1535–45; < Latin symmetria < Greek symmetría. See sym-, -metry]
syn: symmetry, balance, proportion, harmony all denote qualities based on a correspondence or agreement, usu. pleasing, among the parts of a whole. symmetry implies a regularity in form and arrangement of corresponding parts: the perfect symmetry of pairs of matched columns. balance implies equilibrium of dissimilar parts, often as a means of emphasis: a balance of humor and seriousness. proportion implies a proper relation among parts: His long arms were not in proportion to his body. harmony suggests a consistent, pleasing, or orderly combination of parts: harmony of color.

sym·me·try

(sĭm′ĭ-trē)
