What is the difference between a LINE SEGMENT and a LINE?

• Line Segments are two-dimensional, Lines are one-dimensional

• Lines can be represented on single planes; Line Segments can only be represented on multiple planes.

• Line Segments have finite lengths; Lines go on forever.

• Line segments are geometric figures; Lines are not.
