In geometry, an octahedron (plural: octahedra, octahedrons) is a polyhedron with eight faces. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex. A regular octahedron is the dual polyhedron of a cube. … Zobraziť viac Dimensions If the edge length of a regular octahedron is a, the radius of a circumscribed sphere (one that touches the octahedron at all vertices) is Zobraziť viac Octahedra in nature • Natural crystals of diamond, alum or fluorite are commonly octahedral, as the space-filling tetrahedral-octahedral honeycomb. • The plates of kamacite alloy in octahedrite meteorites are arranged paralleling the … Zobraziť viac The following polyhedra are combinatorially equivalent to the regular polyhedron.
