What is a segment

The video tutorial explains the concept of lines in geometry, describing them as straight paths that extend infinitely without thickness and are made up of infinite points. It then introduces line segments, which are portions of lines between two points, and explains how to label them differently from lines by using a straight line on top instead of arrows. The tutorial emphasizes the difference between lines and line segments in terms of measurement and labeling.
