Please try to clarify your question. I don't get the connection between the question title and text. Do you have a link to point us to? – underdark♦ Nov 26 '10 at 7:54
Voted to close because no clarification seems forthcoming and both the title and question are incomprehensible. – whuber♦ Nov 26 '10 at 19:11

Points can not 'intersect'. They are either equal or they are not. If you create a vector based on points p1 and p2 then the vector will 'intersect' both points because that's what the vector was intended to do.

Plus, I don't get how a vector can be compared to a number. – GuillaumeC Nov 26 '10 at 9:51
ok if i sat ab<1 pr ab>1.. what does it mean.. is that mean by point p1 is not at pont p2. – tina Nov 27 '10 at 2:38
if i say vector ab <0.0001 where ab is a vector from point P1 and P2.. what means by ab<0.0001 and ab>-0.0001. – tina Nov 27 '10 at 3:54
