The 20th century saw a succession of generalisations of the idea of a regular polyhedron, leading to several new classes. In the first decades, Coxeter and Petrie allowed "saddle" vertices with alternating ridges and valleys, enabling them to construct three infinite folded surfaces which they called regular skew polyhedra. Coxeter offered a modified Schläfli sy… 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.

WebJul 12, 2024 · Plane angles are the interior angles of all the faces, so there are F * n of them for polyhedra consisting of faces that are n-gons. For example, in a cube there are 6*4=24 of them. 2F+2V-4= 2*6+2*8–4 is 24 as well indeed. Because in any polyhedron, it is a general truth that an edge connects two face angles, it follows that P=2E.
