Coplanar Lines. Coplanar Lines are lines which lie on the same plane. Two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. Lines in three dimensional space are coplanar, only if they are not skewed lines. Two lines which are neither parallel nor intersecting are called skewed lines.
1 Corresponding Angles Postulate If two parallel lines are cut by transversal, then the pairs of corresponding angles are congruent. ( 2 page 135). 3  Corresponding Angle Converse If two lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel.
