kuusikulmaisen

Kuusikulmainen is the Finnish adjective meaning hexagonal or six-angled. It is used to describe objects or shapes that have six angles or six sides. The corresponding noun is kuusikulmio, meaning hexagon. In grammar, kuusikulmainen inflects like other adjectives; for example, genitive singular is kuusikulmaisen, partitive singular kuusikulmaista, and plural forms include kuusikulmaisia. The root kuusikulma- combines kuusi (“six”) and kulma (“angle”).

In geometry, a hexagon is a polygon with six sides. The sum of interior angles in any hexagon is (n−2)×180 degrees, which for n = 6 equals 720 degrees. A regular hexagon has six equal sides and six equal interior angles, each measuring 120 degrees. If sides or angles vary, the shape is irregular. Hexagonal shapes and tilings are common in both natural and applied contexts due to efficient packing and symmetry.

Common contexts for kuusikulmainen include descriptions of patterns, tilings, or objects with a hexagonal geometry. Examples include kuusikulmainen kuvio (hexagonal pattern) in design, kuusikulmainen prisma or kuusikulmainen kappale in descriptive texts, and references to hexagonal shapes in chemistry and crystallography, such as hexagonal rings or lattices. The term is broadly used in technical, educational, and design-related Finnish language.
