Geometry Prisms - Definitions

• A Prism is a polyhedron with two congruent polygonal faces that lie in parallel planes.
• The Bases are the parallel polygonal faces.
• The Lateral Faces are the faces that are not bases.
• The Lateral Edges are the edges between the lateral faces.
• The Slant Height is the length of a lateral edge. Note that all lateral edges are the same length.
• The Height is the perpendicular length between the bases.
• A Right Prism is one in which the angles between the bases and the lateral edges are right angles. Note that in a right prism, the height and the slant height are the same.
• An Oblique Prism is one that is not a right prism.
• The Surface Area of a prism is the sum of the areas of all its faces.
• The Lateral Area of a prism is the sum of the areas of its lateral faces.
