hendecahedron
Definition
Noun (mathematics): A "hendecahedron" is a solid figure with eleven plane faces.
Usage Examples
- (A solid with eleven flat surfaces.)
- (A polyhedron with eleven faces.)
Advanced Usage
- "regular hendecahedron": A hendecahedron with all faces being congruent regular polygons and all vertices identical. (Note: A regular hendecahedron is not possible in Euclidean geometry; this term is sometimes used hypothetically or in abstract contexts.)
- Though a regular hendecahedron cannot exist in three-dimensional space, mathematicians explore its properties in theoretical geometry. (A hypothetical eleven-faced polyhedron with equal faces and angles.)
Variants and Related Words
- Hendecahedral (adj): relating to or having the shape of a hendecahedron.
- The hendecahedral structure of the molecule was confirmed by X-ray crystallography. (Having eleven faces.)
Synonyms
- 11-faced polyhedron: a general term for any solid with eleven faces.
- Undecahedron: an alternate term for hendecahedron (from Latin "undecim" meaning eleven).
