Consider a correctly functioning clock that starts ticking at noon and find the time between noon and 1:00 P.M. when the angle measure between the hands is 90degrees. Lines that are not found on the same plane are called noncoplanar lines. 4. its true explanation:Therefore, skew lines cannot be perpendicular. Two planes that do not intersect are parallel. 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.
