driekante

Driekante is an adjective in Dutch used to describe objects or figures that have three corners or sides, i.e., triangular or three-cornered. In geometry, a driekante figure has three sides and three interior angles; in everyday language, it can describe anything from a driekante figuur to a decorative element shaped like a triangle. The term is derived from the elements drie, meaning "three", and kant, meaning "edge" or "side", with the suffix -e forming an attributive adjective.

Notes: While driekante is understood in many Dutch-speaking regions, it is less common in formal mathematical writing, where driehoekig or driehoekige is preferred. Driekante appears more often in older texts, regional dialects, or Flemish usage and can also be found in compound terms such as driekante figuur, driekante dak or driekante kandelaar, depending on context.

Related terms include driehoek (triangle); driehoekig (triangular); driekant (three-sided figure); driekantigheid (three-sidedness).
