sechsseitiges

Sechsseitiges is a German adjective meaning having six sides. It is used to describe nouns that indicate a shape, figure, or object with six sides. The word is formed from sechs (six) and seitig (sided). As an attributive adjective, its ending changes according to the gender, number, and case of the noun it modifies.

In the neuter singular nominative or accusative, the form sechsseitiges appears before a noun with a definite or indefinite article: for example, ein sechsseitiges Polygon or das sechsseitige Polygon. The ending -es reflects the neuter singular. For feminine or plural nouns, other endings are used, such as eine sechsseitige Form or sechsseitige Vielecke. While rarely nominalized, the adjective can sometimes occur as das Sechsseitige in stylistic contexts.

In geometry, sechsseitiges describes polygons with six sides and is primarily a descriptive term rather than a fixed geometric label. The standard term for a six-sided polygon is Sechseck (or Hexagon in Greek-based usage). In practice, one might say ein regelmäßiges Sechseck to denote a regular hexagon, while sechsseitiges Vieleck or sechsseitiges Polygon emphasizes the six-sided property without adopting a specialized name.

Common phrases include ein sechsseitiges Polygon and ein sechsseitiges Vieleck. See also Sechseck, Vieleck, Polygon, Hexagon.
