This geometry video tutorial provides a basic introduction into lines, rays, line segments, points, and angles. It also explains the difference between the union and intersection symbols and contains a few practice problems associated with it. Lines extend infinitely in both directions. Rays have a common endpoint and extend infinitely in one direction. Line segments have a beginning and an end and possess a definite length. Angles are composed of two rays that meet at a common endpoint or a vertex.
