Hey baz thank you for your reply. You mean Line does not have 2 distinct end points and extends in both directions and denoted by two alphabets like AB. Line segment has 2 distinct end points and does not extend in both directions and denoted by two alphabets AB. Is line and line segment denoted as AB only.
Also here you are talking about Ray also. I didn't understand Ray. I was searching about Ray i found 3 similar terms like this Ray, Half-Line, Line Separation
http://youtu.be/80Gchwo6gHM Half line i can generally say that it is half of the line is this correct? Line separation means line might get separated. You were talking about Ray please tell me in your terms about Ray. So Line is denoted as AB ( no distinct points), Line segment (2 distinct points),Line separation (Line get separated denoted as ?),Half-line (half of the line denoted as ?), Ray (?) If i am wrong please correct me. Have a great day baz.
