line intersections

This question has thrown me off as I realize that lines intersect at only one point.

If two lines intersect in more than one point, then they are which of the following?

Unique
Inconsistent
Parallel
The same
None of these

My thought is none of these but wanted other opinions

Re: line intersections

Hi;

They are the same.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?

Re: line intersections

I guess that makes sense but if it is the same line, it is not intersecting with itself is it? This is where I am confused...

Re: line intersections

The intersection of the set of all the points of a line with itself is the line. But that is not a choice.

Re: line intersections

Hi mom;

I like the fourth choice best. Did you check?
