Are any two lines always coplanar?
No, not always. Skew lines are never coplanar, but parallel lines are.
Is two lines that are transversal always never or sometimes coplanar?
They are always coplanar in Euclidean geometry.
Are two parallel lines always coplanar?
Yes.
Are two parallel lines never coplaner?
Parallel lines are ALWAYS coplanar.
Can two lines be coplanar?
yes, two lines can be coplanar.
Can two lines be coplanar always?
No. Skew lines are never coplanar. Stand in a cuboid room and consider the line where the opposite wall and the floor meet. Consider also the line where the walls behind you and to your right meet. Those two lines are not coplanar.
Is intersecting lines always coplanar?
Yes. The two lines define a plane which they both belong to.
Are two lines that are not parallel coplanar and do not intersect?
are two lines that are not parallel, coplanar, and do not intersect
Do non coplanar lines intersect?
No. If two lines intersect, then they're definitely coplanar.
What are two coplanar lines that never intersect called?
Two coplanar lines that never intersect are called called parallel lines.
What are two lines that are in different planes that do not intersect called?
parralel lines
Are any two pairs of perpendicular lines coplanar?
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
