WebIn geometry, a polyhedron is a three-dimensional object with flat polygonal faces, sharp corners and straight edges. Each side is a flat surface and is without any curved surfaces. The word comes from the Greek 'poly' (stem of many) + 'hedron' (face). So, a polyhedron basically means 'many faced geometric shape.'. 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 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 a solid, forms a convex set.
