| point #1 | A precise location or place on a plane. |
| point #2 | Usually shown by a dot. It is not a thing but a place. |
| line #1 | Geometrical object that is straight, infinitely long, and infinitely thin. |
| line segment | Straight line that links two points without extending beyond them. |
| collinear points | Set of points that lie in a straight line. |
| ray #1 | A line which starts at a point and goes off in a certain direction to infinity. |
| ray #2 | A line with only one end. |
| angle #1 | Two rays with a common end point. |
| angle #2 | Shape formed by 2 lines or rays coming from a common point (the vertex). |
| plane | Imaginary flat surface that is infinitely large with zero thickness. It has no edges. |
| coplanar | Lying in the same plane. |
| line #2 | Intersection of two planes. |
