| Question | Answer |
|---|---|
| Area | The number of square units needed to cover the inside of a region or plane figure. |
| Cone | A 3-dimensional figure with a curved surface, a circular base, and one vertex. |
| Cube | A 3-dimensional figure with six congruent square faces, * vertices and 12 edges |

| Polygon | A closed plane figure formed using line segments that meet only at their endpoints. |
| pyramid | A solid figure with a polygon as a base and triangular shaped faces that share a common vertex. |
| prism | A 3-dimensional figure with two parallel, congruent polygons as bases and parallelograms for faces. |
| perpendicular lines | Lines that meet or cross each other to form right angles. |
| Acute Angle | An angle with a measure greater than 0° and less than 90°. |

| Volume | The number of cubic units needed to fill a 3-dimensional figure or solid figure. |
| Width | The measurement of distance from side to side telling how wide. |
| three-dimensional figure (3-D) | A figure that has length, width, and height. |
