In geometry, a polyhedron (plural polyhedra or polyhedrons; from Greek πολύ (poly-) 'many', and εδρον (-hedron) 'base, seat') is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices. A convex polyhedron is the convex hull of finitely many points, not all on the same … See more Convex polyhedra are well-defined, with several equivalent standard definitions. However, the formal mathematical definition of polyhedra that are not required to be convex has been problematic. Many … See more Many of the most studied polyhedra are highly symmetrical, that is, their appearance is unchanged by some reflection or rotation of space. Each such symmetry may … See more The name 'polyhedron' has come to be used for a variety of objects having similar structural properties to traditional polyhedra. Apeirohedra See more From the latter half of the twentieth century, various mathematical constructs have been found to have properties also present in traditional polyhedra. Rather than confining the … See more Number of faces Polyhedra may be classified and are often named according to the number of faces. The naming system is based on Classical Greek, and … See more A three-dimensional solid is a convex set if it contains every line segment connecting two of its points. A convex polyhedron is a polyhedron that, as … See more Polyhedra with regular faces Besides the regular and uniform polyhedra, there are some other classes which have regular faces but lower overall symmetry. Equal regular faces Convex polyhedra where every face is the same kind of regular … See more WebFeb 3, 2011 · Novel highly symmetric multi-faceted polyhedral Cu 2 O crystals enclosed by controllable high-index facets and different low-index facets have been synthesized via a template-free complex-precursor solution route.
