A '''line''' was described by [[Euclid]] as having "breadthless length." This means that a line in infinitely long, but has no width.  Lines can be considered as curves with infinite radius of curvature.  A line that can be drawn on paper is not actually a line, but a representation of a line.  Two points determine a line.  A line can be broken down into finite [[line segment]]s.
