Any two flat objects sharing space on a plane surface are said to be coplanar. Three types of lines that are coplanar are parallel lines, perpendicular lines, and transversals. These all exist in a single plane, unlike skew lines (which exist in multiple planes).

Are perpendicular lines sometimes coplanar?

Explanation: Perpendicular lines are defined as being co-planar, so therefore they always have to be co-planar or else they would be skew.

Can perpendicular lines be Noncoplanar?

Two lines in the same plane either intersect or are parallel. If two lines intersect and form a right angle, the lines are perpendicular. Skew lines are lines that are non-coplanar and do not intersect. ... Two planes are perpendicular if they intersect and form a right angle.
