I am confused

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 nhi,

"If two lines intersect, then they intersect in exactly one point"
and three noncollinear points define a plane.

Therefore,

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

Unique
Inconsistent
Parallel
The same
None of these

'None of these' is right. You are correct!

'The same plane' is the solution.

Re: I am confused

I would say this means they are the same line and intersect everywhere.
