Lines Line Segments And Rays. A ray is the part of a straight line that extends infinitely in one direction from a fixed point. A complex figure depicts lines, rays, and line segments sharing one or more common points.
Extends in both directions without end (infinitely).
Few more line segments from the above figure are ay, ab, xy, xb, yb, xz. Straight lines, points and rays can be represented in a sheet of paper or on the black board. Line segments are represented by a single overbar with no arrowheads over the letters representing the two endpoints. What i want to do in this video is think about the difference between a line segment, a line, and a ray.
