| Name a segment by naming the two | endpoints in any order and then drawing the symbol above the two endpoints. |
| Segments of equal length are | congruent segments |
| Tick marks are used | to show congruence. |
| Betweenness: If XY + YZ = XZ, then the point Y is | between points X and Z |
| Segment Addition: If point Y is between points X and Z, then | XY + YZ = XZ |
