| bases | One of the two parallel congruent faces of a prism. |
| complementary angles | Two angles are complementary if the sum of their measure is 90. |
| cone | A three-dimensional figure with one circular base connected by a curved surface to a single point. |
| congruent | Having the same measure. |
| cross section | The intersection of a solid and a plane. |
| cylinder | A three dimensional figure with two parallel congruent circular bases connected by a curved surface. |
| edge | The line segment where two faces of a polyhedron intersect. |
| face | A flat surface of a polyhedron. |
| plane | A two-dimensional flat surface that extends in all directions. |
| polyhedron | A three-dimensional figure with faces that are polygons. |
| prism | A polyhedron with two parallel congruent faces called bases |
| pyramid | A polyhedron with one base that is a polygon and three or more triangular faces that meet at a common vertex. |
| scale | The scale that gives the ratio that compares the measurements of drawing or model to measurements of a drawing or model to the measurements of the real object. |
| scale drawings | A drawing that is used to represent objects that are too large or too small to be drawn at an actual size. |
| scale factor | A scale written as a ratio without units in simplest form. |
| scale model | A model used to represent objects that are too large or too small to be built at actual size. |
| scalene triangle | A triangle having no congruent sides. |
| straight angle | An angle that measures exactly 180. |
| supplementary angles | Two angles are supplementary if the sum of their measures is 180. |
| vertex | A vertex of a angle is the common endpoint of the rays forming the angle. |
| vertical angles | Opposite angles formed by the intersection of two lines. Vertical angles are congruent. |
| vertices | Plural of vertex. |
| zero angle | An angle that measures exactly 0 degrees. |
