| base | The base is used as a factor as many times as given by the exponent. |
| cone | A three-demensional figure with one circular base. A curved surface connects the base and vertex. |
| cross section | The intersection of a solid and a plane. |
| cylinder | A solid that has two parallel congruent bases (usually circular) connected with a curved side. |
| edge | Where two planes intersect in a line. |
| face | A flat surface, the side or base of a prism. |
| lateral area | The sum of the areas of the lateral faces of a solid. |
| lateral faces | The lateral faces of a prism, cone, cylinder, or pyramid are all surfaces of the figure except the base or bases. |
| net | A two-dimensional pattern for a three-dimensional figure. |
| perspective | A point of view. |
| plane | A two-dimensional flat surface that extends in all directions and contains at least three noncollinear points. |
