Base of a cylinder | The two congruent and parallel circular regions that form the ends of the cylinder. |
Base of a prism | The two faces formed by congruent polygons that lie in parallel planes, all of the other faces being parallelograms. |
Cone | A three dimensional shape with a circular or elliptical base and one vertex. |
Cube | A regular polyhedron whose six faces are congruent squares. |
Cylinder | A three dimensional object with two parallel, congruent, circular bases. |
Edge | The intersection of a pair of faces in a three dimensional figure. |
Face | One of the polygons that makes up a polyhedron. |
Lateral Faces | In a prism, a face that is not a base of the figure and in a pyramid, faces that intersect at the vertex. |
Net | A two-dimensional figure that has polygons as faces. |
Polyhedron | A three-dimensional figure that has polygons as faces. |
Pyramid | A polyhedron with one base and the same number of triangular faces as there are sides of the base. |
Prism | A polyhedron with two parallel and congruent faces, called bases, and all other faces that are parallelograms. |
