What else can I help you with?
Two lines in the same plane that do not intersect?
They are parallel lines
What is a parallel line?
Two lines that are perfectly straight and will never intersect.
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.
Why is the distance between two lines only defined for parallel lines?
because they never intersect
If two lines are not perpindicular then they are not parallel?
Not necessarily. Consider two lines that intersect at some angle other than 90 degrees. Then the angle of intersection is not 90 degrees means they are not perpendicular. But, because they intersect, neither are they parallel.
Two lines that intersect?
Are non-parallel lines.
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.
Why do two non-parallel lines have to intersect?
The lines have to intersect because lines go on forever and if then are not parallel then they will collide. Even if they are not parallel by one degree they will still intersect.
Where do two distinct parallel lines intersect?
A vertex? In non-euclidean geometry: A two distinct parallel lines intersect in the "Infinity zone"
Can two lines be both non intersecting and non parallel?
no, if two lines are not parallel then the will eventually have to intersect.Alternate perspective:Yes, if two lines are non-parallel, they need not intersect in three dimensional space.
If two lines in the same plane and do not intersect they are called?
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
Are two lines that are not parallel coplanar and do not intersect?
are two lines that are not parallel, coplanar, and do not intersect
When are two lines nonintersecting?
When two lines are parallel, then they do not intersect.
What are two lines that don't intersect?
Parallel lines do not intersect.
Are lines that never intersect parallel or perpendicular?
parallel ============================================= Parallel. _____________________ _____________________ Those two lines will NEVER intersect.
Can two lines be parallel and have the same Y intersect?
Parallel lines are lines that never intersect. So the answer is no.
If two lines do not intersect must they be parallel?
If the two lines lie in the same plane, and they do not intersect, then they are parallel. If they are not in the same plane, and do not intersect, then they are called skew lines.
