zwölfseitige

zwölfseitige is a German adjective meaning "twelve-sided". It is most commonly used in the context of polyhedra, specifically referring to a dodecahedron, a geometric solid with twelve flat faces. A regular dodecahedron has twelve identical regular pentagonal faces. In other contexts, zwölfseitige can describe any object or shape that possesses twelve sides or surfaces. For example, a twelve-sided die, often used in tabletop games, is a zwölfseitige. The term emphasizes the number of sides or faces as a defining characteristic. It is a descriptive term rather than a technical mathematical classification in itself, relying on the context of the object being described.
