Decahedron
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:
Decahedra with irregular faces include:
- Pentagonal trapezohedron – often used as a die in role playing games, known as a d10
- Truncated square trapezohedron
- Enneagonal pyramid
- Ten of diamonds decahedron - a space-filling polyhedron with D2d symmetry
- Chamfered Tetrahedron
