If two lines are skew lines, then they are noncoplanar. For example, see at second image. The planes z =(4x+4y)=-16 \ and \ x-3 ,z=0 are not parallel, so they must intersect along a line that is common to both of them. k parallel m, Given m 1 = 62.5 and m 6 = 118.5 . Hypothesis: two lines are perpendicular Conclusion: they intersect If two lines are perpendicular, then they intersect. Answer: Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions.
