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.
yes
Parallel lines do not intersect.
Two lines cross or intersect at a point.
When two lines intersect they form an axes.
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
they intersect at some point
yes
No--skew lines are nonparallel lines that still do not intersect (in three dimensions or higher).
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
