nouna solid figure bounded by plane polygons or facestype of:
Definition that contains polyhedron
- pyramid a polyhedron having a polygonal base and triangular sides with a common vertex
- prism a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms
- tetrahedron any polyhedron having four plane faces
- dodecahedron any polyhedron having twelve plane faces
- octahedron any polyhedron having eight plane faces
- hexahedron any polyhedron having six plane faces
- concave polyhedron a polyhedron some of whose plane sections are concave polygons
- trapezohedron a polyhedron whose faces are trapeziums
- icosahedron any polyhedron having twenty plane faces
- prismatoid a polyhedron whose vertices all lie in one or the other of two parallel planes; the faces that lie in those planes are the bases of the prismatoid
