Two lines are coplanar if they both have 2 points in the same plane. So in an X,Y,Z
grid, one slope, be it X Y or Z, must be the same for both lines. To find the slope,
use Y1-Y2/X1-X2 or replace one of those values with Z. For this particular example,
it doesn't matter which is on the numerator, because it is a comparison.
================================
Short-cut:
Two lines that intersect are always coplanar.

Can two lines be coplanar?
yes, two lines can be coplanar.
Do non coplanar lines intersect?
No. If two lines intersect, then they're definitely coplanar.
Are any two lines always coplanar?
No, not always. Skew lines are never coplanar, but parallel lines are.
What are two lines that are not coplanar and do not intersect?
Parallel lines.
What is These are lines which intersect two or more coplanar lines?
a transversal
Can two lines be coplanar?
yes, two lines can be coplanar.
Are two lines that are not parallel coplanar and do not intersect?
are two lines that are not parallel, coplanar, and do not intersect
Do non coplanar lines intersect?
No. If two lines intersect, then they're definitely coplanar.
Are any two lines always coplanar?
No, not always. Skew lines are never coplanar, but parallel lines are.
What are two coplanar lines that never intersect called?
Two coplanar lines that never intersect are called called parallel lines.
Are any two pairs of perpendicular lines coplanar?
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
Two coplanar lines that do not intersect?
parallel lines
What are two lines that are not coplanar and do not intersect?
Parallel lines.
What are two coplanar lines that do not intersect?
Parallel Lines or Skew Lines.
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.
What are Lines which intersect two or more coplanar lines?
transversal
What is These are lines which intersect two or more coplanar lines?
a transversal
