A solid having twelve faces.
A solid figure contained by 12 equal and equilateral triangles.
Twelve sided polyhedron; all sides are equidimensional and either rhombic or pentagonal. If the dodecahedron is composed of rhombs, it is known as a rhombic dodecahedron, or simply as a dodecahedron. If it is composed of pentagons, it is known as a pentagonal dodecahedron or pyritohedron. Minerals shaped as dodecahedrons belong to the isometric system. Minerals with this property are described as dodecahedral.
any polyhedron having twelve plane faces
a solid figure contained by twelve equal, equilateral and equiangular pentagons
a solid figure enlosed by twelve pentagons that are equal, equal-sided, equal-angled
a twelve sided geometric shape similar to a ball
Polyhedron of 12 Faces; if Regular, 1 of the 5 Platonic Solids
It is a term given to twelve sided polyhedron where all the sides are equidimensional and either rhombic or pentagonal. If composed of rhombs, is known as a rhombic dodecahedron or just dodecahedron and known as pentagonal dodecahedron if composed of pentagons. Minerals shaped such belongs to the isometric system.
(do-dec´-a-he´-dron) A crystal form with 12 faces that are either pentagonal or rhombic. Each face is parallel to one crystallographic axis and intersects the other two at equal distances.
A dodecahedron is a twelve-sided geometric solid whose faces are pentagons.
A twelve-sided solid, with each side being five-sided or pentagonal. One of the " platonic primitives" Aladdin4D can generate. Dodecahedron
A Platonic solid consisting of twelve pentagonal faces, 30 edges, and 20 vertices.
One of the seven basic forms in the highest symmetry ("hexoctahedral") class of the cubic, or isometric, crystal system. It has 12 rhomb-shaped faces, each of which intersects two of the crystallographic axes and is parallel to the third. This form is uncommon in gem diamonds.
Solid figure comprised of 12 adjoining plane surfaces.
A dodecahedron is any polyhedron with twelve faces, but usually a regular dodecahedron is meant: a Platonic solid composed of twelve regular pentagonal faces, with three meeting at each vertex. It has twenty vertices and thirty edges. Its dual polyhedron is the icosahedron.
