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''.

* A line segment is 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. [http://strader.cehd.tamu.edu/Mathematics/Geometry/PolygonLesson/Details/line_segment.html]
