Segment notation uses a single overbar above the two endpoint letters, while line notation uses a double-headed arrow above the two point letters. A segment has two endpoints and is finite, whereas a line extends infinitely in both directions.
Conditions: The object is either a segment or a line.; Two points are used for naming.
