Question | Answer |
A solid that is bounded by polygons, called faces, that enclose a single region of space. | Polyhedron |
The polygons that enclose the polyhedron | Face |
A line segment formed by the intersection of two faces of a polyhedron. | Edge |
A point where three or more edges of a polyhedron meet. | Vertex |
A polyhedron whose faces are all congruent regular polygons. | Regular 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. | Convex |
The intersection of a plane and a solid. | Cross Section |
Five regular polyhedra, named after the Greek mathematician and philosopher Plato, including a regular tetrahedron, a cube, a regular octahedron, a regular dodecahedron, and a regular icosahedron. | Platonic Solids |

A polyhedron with eight faces. | Octahedron |
A polyhedron with twelve faces. | Dodecahedron |
A polyhedron with twenty faces. | Icosahedron |
A polyhedron with two congruent faces, called bases, that lie in parallel planes. The other faces, called lateral faces, are parallelogram formed by connecting the corresponding vertices of the bases. | Prism |
On a prism, these are the faces that have only TWO of the same polygonal shape. On a pyramid, these are the faces that have only ONE polygonal shape. | Bases |
These are the faces that connect the two bases. | Lateral Faces |
A prism whose lateral edges are perpendicular to both bases. | Right Prism |
A prism whose lateral edges are not perpendicular to the bases. | Oblique Prism |

The sum of the lateral area of the cylinder and the areas of the two bases. | Surface Area of a Cylinder |
A polyhedron in which the bases is a polygon and the lateral faces are triangles with a common vertex. | Pyramid |
A pyramid such that the base is a regular polygon and the segment from the vertex to the center of the base is perpendicular to the base. | Regular Pyramid |
A solid with a circular base and a vertex that is not in the same plane as the base. | Circular Cone |
The area of the curved surface of a cone. | Lateral Surface of a Cone |
