# Line segment

part of a line that is bounded by two distinct end points; line with two endpoints

In geometry, a line segment is a line between two different endpoints. It is represented by a line above the symbols of the two endpoints (such as ${\displaystyle {\overline {AB}}}$).[1] Unlike a line, a line segment does not extend beyond the endpoints.[2]

An example of a line segment is a side of a triangle. If the endpoints are on a curve, like a circle, then the line segment is called a chord.
