Repeating something that didn't answer the questions the first time, doesn't answer the questions the second time, either.
Ignoring the question for the second time does not giving to the chance to escape from a clear answer.
I am closing this question on you in such a way the will not give you any chance to escape form a clear answer.
It goes like this:
1) w.r.t is not a pert of my question anymore.
2) "Endless (open) line" or "(open) endless line" are the same 1-dim thing.
First, I give you a clue by using your own words:
jsfisher said:
Consider any line in a plane. The line (endless, you may note) is an edge. It is the edge of the two half-planes delineated by the line.
By using your example of an endless open line that is used as an edge of the two half-planes delineated by that line, you actually accept the notion of an endless plane, such that a single endless (open) line is found on it.
Now all we have to do is to think about an endless (open) plane, where no other dimension accept 2-dim, is considered.
The same abstraction holds also in the case of an endless (open) line, where no other dimension accept 1-dim, is considered.
By following this abstraction, please answer to my question, which is:
EDIT: What is the difference between an endless (open) line (where only a 1-dim is considered) and a (open) line segment?
