simetris

Simetris is a term used in Indonesian and Malay languages to denote symmetry, the property of a figure or object that is invariant under a set of transformations. The word derives from Greek symmetria through Latin and into modern languages, and in practice simetris describes the balance and proportional correspondence of parts relative to an axis, center, or repeating motif.

In mathematics, symmetry means invariance under a group of transformations. Common types include reflectional symmetry (mirror symmetry), rotational symmetry (an object is unchanged after rotation by a certain angle), translational symmetry (patterns that repeat in space), and glide reflection (a reflection followed by a translation). Objects may have point symmetry, axis symmetry, or translational symmetry, and their overall structure can be described by symmetry groups.

In nature and science, symmetry appears in biology (bilateral symmetry of humans, radial symmetry in starfish), crystallography (lattices with rotational and translational symmetry), and physics (conservation laws often relate to underlying symmetries). In design and culture, simetris is used to create visual balance, from architectural facades to geometric tiling and corporate logos.

Terminology: simetris is often used as a general adjective meaning “symmetric” or “having symmetry,” and is common in technical writing within Indonesian contexts. The broader concept remains a cornerstone across disciplines, guiding analysis of form, function, and pattern.
