In geometry, a polyhedron (plural polyhedra or polyhedrons) is a threedimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.The word polyhedron comes from the Classical Greek πολύεδρον, as poly(stem of πολύς, "many") + hedron (form of ἕδρα, "base" or "seat").. A convex polyhedron is the convex hull of finitely many points, not all on ...

A polyhedron is a solid with flat faces (from Greek poly meaning "many" and hedron meaning "face"). Each face is a polygon (a flat shape with straight sides). Examples of Polyhedra: Cube Its faces are all squares. Triangular Prism Its faces are triangles and rectangles. Dodecahedron

Polyhedron. The word polyhedron has slightly different meanings in geometry and algebraic geometry.In geometry, a polyhedron is simply a threedimensional solid which consists of a collection of polygons, usually joined at their edges.The word derives from the Greek poly (many) plus the IndoEuropean hedron (seat). A polyhedron is the threedimensional version of the more general polytope (in ...

Polyhedron, In Euclidean geometry, a threedimensional object composed of a finite number of polygonal surfaces (faces). Technically, a polyhedron is the boundary between the interior and exterior of a solid. In general, polyhedrons are named according to number of faces. A tetrahedron has four

A polyhedron is a 3dimensional solid made by joining together polygons. The word 'polyhedron' comes from two Greek words, poly meaning many, and hedron referring to surface. The polyhedrons are defined by the number of faces it has.

Assuming that NETS polyhedra are defined in this way, if S is a polyhedron in 3space or in the boundary of a 2, 3, or 4dimensional convex polytope, then it can be shown that, regardless of our choice of coefficient group G, the polyhedron S is NETS just if S is contractible 10 (i.e., just if S can be continuously deformed over itself to a ...
