A line segment is a finite, unbroken portion of a line (lines extend infinitely in both directions. For example, the real line extends through all the real numbers from negative infinity to positive infinity). A line segment of the real line is more commonly known as an interval, [a,b] for some real numbers a≤b.
Alternatively, a line segment can be thought of as the set of all points that lie on the line between two given points. The two given points are called the end points of the line segment. [1]
