tenfaced

Tenfaced is a term used to describe something that has ten faces. In geometry, ten-faced polyhedra are collectively referred to as decahedra, and they encompass any polyhedron with ten faces. The most familiar ten-faced solid in mathematics and gaming is the pentagonal trapezohedron, which is the dual of a pentagonal antiprism. This shape features ten congruent kite-shaped faces and two opposite vertices where five faces meet, giving it a balanced, symmetric form. The pentagonal trapezohedron is also the standard design for a ten-sided die used in tabletop games.

Beyond strict geometry, tenfaced can appear in non-technical contexts as a descriptive label or as a proper name in fiction, music, or digital media. In such uses, it may denote a character, entity, or artwork imagined to possess ten faces or ten distinct aspects. Because these usages are creative and vary by source, there is no single canonical definition.

Etymology and related terms: the word tenfaced combines the numeral ten with faced, reflecting the presence of ten faces. It is related to the broader category of decahedra (ten-faced polyhedra). A well-known concrete example associated with the term is the pentagonal trapezohedron, which underpins the common ten-sided die used in many games.

Overall, tenfaced serves as both a geometric descriptor and a flexible label in culture, primarily anchored by the existence of decahedra in mathematics and the pentagonal trapezohedron in dice design.
