In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra, and none are regular, so this name does not identify a specific type of polyhedron except for the number of faces. Some decahedra have regular faces: Octagonal prism (uniform 8-prism) Square antiprism (uniform 4-antiprism)
The pyritohedron has a geometric degree of freedom with limiting cases of a cubic convex hull at one limit of collinear edges, and a rhombic dodecahedron as the other limit as 6 edges are degenerated to length zero. The regular dodecahedron represents a special intermediate case where all edges and angles are equal.

May 21, 2022 · Concave - shapes that follow the concave property of 2-dimensional geometry in 3-dimensional space. Nets are used when constructing polyhedra out of a single, contiguous, piece of material. The various polygons are laid out together, edges touching, to be cut out and folded together.
