13.3.6 Positions of Point-and-Line and Line-and-Line
Core ideaA point either sits on a line or lies off it; two lines either cross at a single point or run parallel and never meet.
Module goal. Zoom in on the most basic straight figures, tell apart the three siblings (line, ray, segment), and grasp their basic properties as the foundation for every geometric construction ahead.
