Polyhedra and Prisms

Polyhedra and Prisms. Definitions. A polyhedron is a solid, bounded by polygons (called faces), that enclose a (single) volume, or region of space. An edge is a line formed by the intersection of 2 faces. A vertex is a point where 3 or more edges come together.

The Geometry of Solids

The Geometry of Solids. Section 10.1. A solid formed by polygons enclosing a region is called a polyhedron. The flat surface (or polygon) are called a face . The segment where two faces (or polygons) meet is called an edge . The point of intersection of three edges is called a vertex.
