Polyhedron
A solid bounded by at least four polygonal faces.
Face
A polygonal surface of a solid figure.
Vertex of a Polyhedron
The point at which three or more edges meet.
Edge
A line segment where two faces of a polyhedron meet.
Diagonal of a Polyhedron
A line segment joining two vertices that are not on the same face.
Prisms
Polyhedra bounded by two parallel polygonal faces and several parallelogram faces. The side edges are all parallel and equally long.
The Height of the Prism
Perpendicular distance between the two parallel faces.
Right Prisms
A prism is a right prism if the sides are rectangles (or squares). In right prisms, the side edges are perpendicular to the bases. If the sides are not rectangles (rhomboids, for example), it is an oblique... Continue reading "Understanding Polyhedra: Definitions, Types, and Properties" »
