Polyhedron angle
WebLooking straight at the vertex, if β is the projected angle between the edges: β = 2π/ n. ½β … 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. Cubes and pyramids are examples of convex polyhedra.

Webdihedral angles as a list of angles or set of rules indexed by adjacent face indices "Dual" polyhedron dual as an entity standard name, entity, graphic, graphics complex, polyhedron, or scale "Edges" edges as an indexed list, count, list of unique lengths, rule list, lines, graphic, graphics complex, or image "Faces" WebA polyhedron is a three-dimensional solid bounded by a finite number of polygons called faces. Points where three or more faces meet are called vertices. Line segments where exactly two faces meet at an angle are called edges. The vertices and edges of the polyhedron make a graph called the graph of the polyhedron.
