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

Hi;

They are the same.

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...

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

Hi mom;

I like the fourth choice best. Did you check?

Answer is "the same" if two lines intersect on more then one point then they are in the same.
