Parallel and Perpendicular Line Segments


Line segments - a line with a beginning and an end. A piece of a line. You know a line ends when it has dots at each end.
Line segments are labeled with letters.

Intersecting - lines that cross or meet.


Parallel - describes lines in the same plane that never cross, or intersect
- they are marked using "arrows"


Perpendicular
