FranNO!!! Because they can be in different planes.

What is the common point at which two lines meet?
point I believe the word you're looking for is "intersection". Two non-parallel lines that lie in the same plane will have one point in common where they cross, and that point is the intersection.
What are two coplanar lines called that have no points in common?
Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
If two lines lie in the same plane and have more than one point in common they must be parallel or intersecting?
Two straight lines in the same plane can't possibly have more than one point in common, unless they are both the same line. If they're parallel, they have no common points. If they're not parallel, then have exactly one common point. If they're the same line, then every point on one line is also on the other one.
Does parallel lines always have the same slope?
Yes, that's what makes them parallel lines - they have the same slope. So they never will intersect with each other. If a set of lines didn't have the same slope, at some point they would intersect and thus would not be parallel.
What do two lines intersect at?
two lines intersect at a single point in a 2D space assuming they are not parallel. in 3D space they can intersect again at a single point, or an infinite amount of points.
Lines that have no point in common?
parallel
Parallel lines are defined as lines that have only one point in common?
No, parallel lines never intersect, so they do not have any points in common. Intersecting lines have one common point.
Lines that have one point in common?
Intersecting lines. If they have only one point in common, then they are also non-parallel.
Two coplanar lines with no point in common are?
parallel
What do parallel lines have?
No point in common. That is correct. More common explanation is that even if you extend the lines in either direction, they would not touch (i.e. have a common point.)
Do lines that aren't parallel always intersect?
Yes, they do. By definition, lines that never intersect must be parallel, so all non-parallel lines must intersect at some point. Given that they are normal lines (y=mx+b) they will always have a point that suffices the equation when they are set equal to each other.
What would happen if parallel lines weren't parallel?
They would 'intersect'. ('cross', have one point in common)
Is a line parallel to itself?
Two lines are not parallel if they have exactly one point in common; otherwise they are parallel. So this means a line is parallel to itself!
What is the common point at which two lines meet?
point I believe the word you're looking for is "intersection". Two non-parallel lines that lie in the same plane will have one point in common where they cross, and that point is the intersection.
Lines with one point in common?
Two lines with one point in common are said to intersect at that point. Any two straight lines with infinite length will eventually intersect each other, unless they are parallel to each other.
What are lines that have one point in common?
Lines that have one point in common are said to intersect one another at that point. Almost all straight lines of infinite length intersect one another, unless they are parallel to each other.
What are two coplanar lines called that have no points in common?
Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
