Because of the way parallel lines are defined. Parallel lines never meet, but to qualify as parallel lines, additional conditions may apply. From Wikipedia: "Two lines in a plane that do not intersect or meet are called parallel lines." Emphasis added.

Are parallel lines also called skew lines?
No. Skew lines are lines in different planes that are parallel.
What is the name of two lines that do not intersect not are parallel?
Skew lines
What do skew lines look like?
Two or more lines that do not intersect and are not parallel.
Are two lines parallel to the same plane parallel to each other?
Not necessarily. They could be skew lines, and satisfy these conditions.
If two coplanar lines do not intersect then they must be what?
Skew. * * * * * FALSE. In fact, if they are skew, they must intersect. They have to be parallel for them not to intersect.
Are skew lines never parallel?
Correct! Skew lines can never by be parallel.
Are parallel lines also called skew lines?
No. Skew lines are lines in different planes that are parallel.
Skew lines and parallel lines exactly the same?
Skew lines are not parallel. Parallel lines are across from each other in some way and are exactly parallel.
Are skew lines parallel?
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
Are two lines that do not intersect skew?
Two lines that are not parallel and do not intersect are skew. If the non-intersecting lines are in the same plane then they are parallel.
What are skew lines?
skew lines are noncoplanar lines, which means they aren't parallel and they also don't intersect skew lines do not intersect and are not coplanar
How is skew lines are different from parallel lines?
Skew lines are lines that lie on separate planes. and do not intercept parallel lines that are sometimes on the same plane, but don't intersect
What are lines that are not parallel and never intersect?
skew lines
What are lines that do not intersect but are not also parallel?
Skew lines.
What are coplanar lines that do not intersect?
Parallel Lines or Skew Lines.
Are parallel skew?
No--skew lines are nonparallel lines that still do not intersect (in three dimensions or higher).
Are skew lines coplanar?
Skew lines are noncoplanar; therefore they're not parallel & don't intersect.
