 Cube A regular polyhedron with six faces, all of which are congruent squares. Cone A surface that includes a simple closed curve and the segments that join all the points on that curve with a single fixed point not in the plane of the curve. Cylinder A geometric surface composed of two congruent simple closed curves lying in parallel planes and segments of parallel lines joining the curves. Face A polygon in a polyhedron. Edge The intersection of two polygons in a polyhedron. Polyhedron A simple closed surface composed of regions of intersecting planes--these regions are polygons. Radius of a Sphere A segment with one endpoint at the center of a sphere and the other endpoint on the sphere. Prism A polyhedron composed of two congruent polygons that lie in parallel planes and the segments that are part of parallel lines that join the congruent polygons. Pyramid A polyhedron composed of a polygon and the segments that join that polygon with a fixed point not in the plane of the polygon. Radius of a Sphere A segment with one endpoint at the center of a sphere and the other endpoint on the sphere. Regular Polyhedron A polyhedron whose faces are congruent regular polygons Regular Pyramid A pyramid whose base is a regular polygon and whose altitude intersects the plane of its base at the center of the base. Right Circular Cone A circular cone whose altitude intersects with the plane of the base at the center of the base. Right Circular Cylinder A circular cylinder whose lateral edges are perpendicular to the planes that contain the bases. Sphere A surface whose points all lie an equal distance from a fixed point in space.
