If lines neither intersect nor are parallel, then they must be drawn in 3D space, or a higher dimension.(These lines are called skew lines)
Perpendicular lines intersect at a 90 degree angle. Parallel lines do not intersect, nor would they ever intersect if continued infinitely.
Diagonal
Lines that are neither parallel nor perpendicular.
Are very common but do not have any particular name. Sit in the corner of a cuboid room. Consider one line which is defined by the floor and the wall on your left. Consider the other as that formed by the ceiling and the wall on your right.
No. Normally, two lines will uniquely identify a plane, unless they happen to be parallel. If you add a third line, it will usually not be in the same plane.* * * * *Not quite. Two lines that meet will uniquely identify a plane. But you can have lines that are neither coplanar nor parallel.For example, consider a cube and think of the line defined by the front bottom and one of the back verticals. Neither parallel, nor coplanar.
SKEW LINES are neither parallel nor intersecting.
No. Lines are infinite, so if they are not parallel, they have to intersect at some point on the plane.
Perpendicular lines intersect at a 90 degree angle. Parallel lines do not intersect, nor would they ever intersect if continued infinitely.
No, oblique lines are neither parallel nor perpendicular
Then they are not parallel, nor skew (in 3D).
A system of equations will intersect at exactly one point if the equations represent two lines that are neither parallel nor coincident, meaning they have different slopes. In this case, there is a unique solution to the system. If the lines are parallel, they will not intersect at all, and if they are coincident, they will intersect at infinitely many points.
Diagonal
Noncoplanar lines cannot intersect because they exist in different planes and do not share a common point. However, they can be skew lines, which means they are neither parallel nor intersecting. In three-dimensional space, two lines are only able to intersect if they lie in the same plane. Therefore, it is geometrically impossible for two noncoplanar lines to intersect.
Skew Lines. :)
parallel
Lines that are neither parallel nor perpendicular.
A pentagon is neither a perpendicular nor a parallel line; it is a five-sided polygon. Perpendicular lines intersect at a right angle, while parallel lines run alongside each other without ever meeting. The concept of perpendicularity and parallelism applies to lines, not shapes like pentagons.
