Skew lines
They are parallel lines
Two lines that are perfectly straight and will never intersect.
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.
because they never intersect
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.
Are non-parallel lines.
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.
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.
A vertex? In non-euclidean geometry: A two distinct parallel lines intersect in the "Infinity zone"
Two non-parallel lines in a plane will intersect at exactly one point. This is because non-parallel lines have different slopes, which means they will eventually cross each other. If the lines were parallel, they would never meet. Thus, the intersection of two non-parallel lines is a unique point.
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.
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
When two lines are parallel, then they do not intersect.
Two non-parallel lines intersect at exactly one point. This is because non-parallel lines, by definition, will eventually cross each other unless they are coincident (which means they lie on top of each other). In the case of non-parallel lines, they will always meet at a single unique point in a two-dimensional plane.
Parallel lines do not intersect.
