WebThe word polyhedron has slightly different meanings in geometry and algebraic geometry. In geometry, a polyhedron is simply a three-dimensional solid which consists of a collection of polygons, usually joined at their edges. The word derives from the Greek poly (many) plus the Indo-European hedron (seat). A polyhedron is the three-dimensional version of the … WebThe ﬁrst two polyhedra are topologically more complex and have closed paths which can not be contracted to a point within the polyhedron. Topologists know that the Euler characteristic is 2− 2g, where g is the number of ”holes”. The ﬁrst two have 4 holes. Theorem of Cauchy: There are exactly 4 non-convex reg-ular polyhedra.
