re: Question about terminology | Comment 2 of 8 |
(In reply to Question about terminology by Larry)

My reply to you in email was:
If I was to consider that question in terms of the crossing of two roads then I have one intersection.  Use that concept in the problem.
In the queue Jer was discussing segments.  In my mind then, two lines crossing result in 4 segments.  I hope that answers your question.
