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?*

*UniqueInconsistentParallelThe sameNone of these*

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

'The same plane' is the solution.

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