Mathigon: Geometry: Polygons and Polyhedra: Polyhedra

Curated by ACT

This lesson focuses on polyhedra; a polyhedron (the plural is polyhedra) is a 3-dimensional solid object that is made up of polygons. Euler's Polyhedron Formula: In every polyhedron, the number of faces (F) plus the number of vertices (V) is two more than the number of edges (E). In other words, F+V=E+2.
