WebA polyhedron is said to be a regular polyhedron if its faces are made up of regular polygons and the same number of faces meet at each vertex. If the line segment joining any two points on the surface of a polyhedron entirely lies inside or out the polyhedron then it is called a convex polyhedron. WebA regular polyhedron is a polyhedron whose symmetry group acts transitively on its flags.A regular polyhedron is highly symmetrical, being all of edge-transitive, vertex-transitive and …

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 plane. … See more Convex polyhedra are well-defined, with several equivalent standard definitions.

WebFor 2D, the task is to identify reflex vertices, and split the polygon into two by creating a new edge (and possibly new vertices) from that reflex vertex, and continuing until you are left with no reflex vertices (and hence all-convex polygons). Polygon Decomposition by J. Mark Keil contains the following algorithm (in unoptimised form):
