| Term | Definition |
|---|---|
| area | the measure of the interior surface of a two dimensional figure |
| center | the point of which all points on a circle are the same the distance |
| circle | the set of all points in a plane that are the same distance from a given point called the center |
| circumference | the distance around a circle |
| composite figure | a figure that is made up of two or more figures |
| composite solid | an object that is made up of more than one solid |
| cone | a three dimensional figure with one circular base connected by a curved surface to a single point |
| cylinder | a three dimensional figure with two parallel congruent circular bases connected by a curved sufac |
| diameter | the distance across a circle through its center |
| face | a flat surface of a polyhedron |
| hemisphere | one of two congruent halves of a sphere |
| lateral face | in a polyhedron, a face that is not a base |
| pi | the ratio of the circumference of a circle to its diameter. The value of pi is 3.145926, which = 3.14 or 22/7 |
| prism | a polyhedron with two parallel congruent faces called bases |
| pyramid | a polyhedron with one base that is a polygon and three or more triangles faces that meet at common vertex |
| radius | the distance from the center of the circle to any point on the circle |
| regular pyramid | A pyramid whose base is a regular polygon and in which the segment from the vertex to the center of the base is the altitude |
| semicircle | Half of a circle |
| slant height | the height of each lateral face |
| sphere | The set of all points in space that are a given distance from a given point called the center |
| surface area | The sum of the areas of all the surfaces of a three dimensional figure |
| volume | The measure of the space occupied by a solid. Standard units of measure are cubic units |
