| postulate 1 | unique line postulate |
| postulate 2 | line/ two distinct pts. postulate |
| postulate 3 | unique plane postulate |
| postulate 4 | plane/ three noncollinear points postulate |
| postulate 5 | 2 pts. plane/ line in plane postulate |
| postulate 6 | 2 planes intersect/ line postulate |
| post. one | through 2 distinct pts., there is exactly one line |
| post. two | a line contains at least two distinct points |
| post. three | through three noncollinear points there is exactly one plane |
| post. four | a plane contains at least three noncollinear points |
| post. five | if two distinct points lie in a plane, then the line joining them lies in that plane |
| post. six | if two distinct planes intersect, then their intersection is a line |
| collinear points | points that lie on the same line |
| noncollinear points | points that dont lie on the same line |
| coplanar points | points that lie on same plane |
| noncoplanar points | points that dont lie in same plane |
