| 1 | Cartesian coordinate system | 
 
 
| 3 | A figure where all points are collinear | 
 
 
| 4 | 2 angles that share a common vertex but do not overlap | 
 
 
| 5 | A dot on a coordinate point representing a coordinate | 
 
 
| 6 | A line, ray, or segment that is an intersection at a midpoint | 
 
 
| 7 | A ray that is the interior of an angle and divides two angles equally in half | 
 
 
| 8 | a collection of ALL the possible points | 
 
 
| 10 | Named after a Greek mathematician Euclid of Alexandria | 
 
 
| 11 | Convex set | 
 
 
| 12 | From postulates these can be proven true | 
 
 
| 13 | Four non-coplanar points that determine space | 
 
 
| 18 | A figure that is 2D and all of the points on the figure are the same distance from a given point | 
 
 
| 19 | Two rays that have the same endpoint | 
 
 
| 24 | flat surface that has no physical features and goes in all direction; it can contain coordinates | 
 
 
| 26 | a dense figure with a point that has no length or width and always represents the shortest past between two points | 
 
 
| 32 | a part of the line with only two endpoints and all of the point in between those two points | 
 
 
| 33 | A figure where all points lie on the same plane | 
 
 
| 34 | An object | 
 
 
| 36 | Rise over run | 
 
 
| 37 | It shares the same endpoint but no other point is common, so that all the points a collinear | 
 
 
| 38 | Assumptions that are made from a point, line, and plane | 
 
 
| 39 | postulate that is between two points on a line |
