| Three-dimensional figure | Spacial figures, like buildings, that do not lie in flat plane. |
| Face | A flat surface on a 3-D figure. |
| Prism | A 3-D figure with 2 parallel and congruent polygonal faces, called bases. The faces of a prism are always rectangular. |
| Edge | A segment where two faces of a 3-D figure meet. |
| Cube | A rectangular prism whose faces are squares. |
| Pyramid | A 3-D figure with only one base. The base is a polygon and the other faces are triangles that join up at a vertex. |
| Cone | A 3-D figure with one circular base and one vertex. |
| Cylinder | A 3-D figure with two circular, parallel, and congruent bases. |
| Net | A flat pattern that forms the surface area of a 3-D figure. |
| Volume | The number of cubic units contained within a 3-D figure. |
| Perfect Square | A number that is the square of an integer. (Ex. 25) |
| Square Root | A number, which when multiplied by itself, gives the given number. |
| Leg | The two shorter sides of a right triangle, which create the right angle. |
| Hypotenuse | The longest side of a right triangle, opposite the right angle. |
| Bases | The two parrallel and congruent polygonal faces of a prism. |
| Sphere | A 3-D, circular figure which has no base. |
| Surface Area | The sum of the areas of the faces and bases of a 3-D figure. |
| Cubic Unit | A cube whose edges are one unit long. |
