Polyhedron
A solid that is bounded by polygons that enclose a single region of space.
Face
A polygonal side of a polyhedron.
Edge
A line segment formed by the intersection of two faces of a polyhedron.
Vertex
A point where three or more edges meet in a polyhedron.
Base
A polygon that is used to name the polyhedron.
Regular Polyhedron
A polyhedron whose faces are all congruent regular polygons.
Convex Polyhedron
A polyhedron such that any two points on its surface can be connected by a line segment that lies entirely inside or on the polyhedron.
Concave Polyhedron
