| Term | Definition |
|---|---|
| point | A location in space that is represented by a dot and has no dimension |
| line | one dimensional geometric figure that extends in two opposite directions without end. |
| plane | A flat surface made up of points that has two dimensions and extends without end and is represented by a shape that looks like a floor or wall |
| collinear points | points that lie on the same line |
| coplanar points | points that lie in the same plane |
| line segment | consists of two endpoints and all the points between them |
| endpoints | points that represent the ends of a line segment or ray |
| ray | a geometric figure that consists of the endpoint A and all points on line AB that lie on the same side of point as point B |
| opposite rays | If point C lies on line AB between A and B, then ray CA and ray CB are opposite |
| intersection | the set of points two or more geometric figures have in common |
