The four relationships two lines in space can have are perpendicular, parallel, skew, and intersecting.
perpendicular refers to when lines are crossing each other making four ninety degree angles.
Parallel lines have the same slope and therefore remain the same distance from each other forever; they never touch.
Intersecting lines cross without making ninety degree angles.
Skew line are lines that do not intersect and are also not parallel. Its like a bridge. cars drive across it and do not hit the cars below although from a aerial view they are in the same place. Because of this phenomenon skew lines cannot exist in a two dimensional situation. Skew lines can only be present in 3 or more dimensional situations.
- If you're working on a single sheet of paper (2-D), then you can draw four lines that intersect in 1, 2, 3, 4, 5, or 6 points. - If in 3-D space, then you can also draw four lines that don't intersect at all.
they share 2 points
In 2-dimensional space they must be parallel. In 3-d space they be parallel or skew lines I believe.

A measure is the space between 2 bar lines in music.

Oh, dude, a 4-point star has 4 lines of symmetry. It's like looking in a mirror and seeing four perfect reflections of yourself, except you're a star. So, if you're ever feeling a bit asymmetrical, just remember, even stars have their symmetrical moments.

Four of them.
yes
Lines are one-dimensional objects but they can be in 2-dimensional - or even 20-dimensional) space.
