In geometry, a rhombohedron (also called a rhombic hexahedron[1][2] or, inaccurately, a rhomboid[lower-alpha 1]) is a special case of a parallelepiped in which all six faces are congruent rhombi.[3] It can be used to define the rhombohedral lattice system, a honeycomb with rhombohedral cells. A cube is a special case of a rhombohedron with all sides square.
Rhombohedron | |
---|---|
Type | prism |
Faces | 6 rhombi |
Edges | 12 |
Vertices | 8 |
Symmetry group | Ci , [2+,2+], (×), order 2 |
Properties | convex, equilateral, zonohedron, parallelohedron |
The rhombohedron has two opposite vertices at which all angles are equal. If this angle us acute then the rhombohedron is long and thin (prolate), if obtuse then it is low and wide (oblate).
