Things to remember about points, lines, segments, rays and planes:
1. It takes __________ points to name a line, ray or segment.
Line AB: __________
**Exception: You may use a lower case, cursive/italic letter to name a line. (This letter
is not a point.)
__________
Segment AB: __________

**A plane may also be named using a
capital cursive/italic letter. (This letter
not a point.
____________________
3. The intersection of two planes is a __________.
