When two lines are parallel, then they do not intersect.
Skew lines are nonintersecting, nonparallel lines - in other words, lines that aren't part of the same plane.
The answer is four. Wish I could draw a picture.
If the planes are non-intersecting, then they're parallel. Any line that intersects one of them intersects both of them.
Two parallel lines.
yes, two lines can be coplanar.
If they are set next to each other and never cross.Edit by Gamerkid26:_________________ Those two lines are parallel.// Those two lines are also parallel.So are those two.\\ And those two./\ These lines are NOT parallel.======================
Two lines cross or intersect at a point.
Two lines that do not intersect on the same plane are Parallel lines.
Two lines intersect at a point
An ellipse has two lines of symmetry.
a cirsquare
Not if they are straight lines.
