In dictionaries:
convex polyhedron
Solid with flat polygonal faces.
Regular polyhedron
Solid with congruent faces, vertices.
simple polyhedron
Solid with flat polygonal faces.
dual polyhedron
(mathematics) Either of a pair of polyhedra in which the faces of one are equivalent to the vertices of the other.
concave polyhedron
Solid with inward-curving faces.
Spherical polyhedron
In geometry, a spherical polyhedron or spherical tiling is a tiling of the sphere in which the surface is divided or partitioned by great arcs into bounded regions called spherical polygons.
flexible polyhedron
In geometry, a flexible polyhedron is a polyhedral surface without any boundary edges, whose shape can be continuously changed while keeping the shapes of all of its faces unchanged.
regular convex polyhedron
Uniform, equilateral faces; symmetrical solid.
Uniform polyhedron
In geometry, a uniform polyhedron has regular polygons as faces and is vertex-transitive—there is an isometry mapping any vertex onto any other.
star polyhedron
(geometry) A polyhedron that is partially nonconvex.
