There are six surfaces on the prism shown, so youll definitely be able to find other coplanar lines! We want the converse of that, or the same idea the other way around: If a transversal cuts across two lines to form two congruent, corresponding angles, then the two lines are parallel. The question is a true and false. If it is true, explain why and/or cite a Theorem. Sometimes C. Never. Coplanar lines in vector and coordinate geometry We will be reintroduced to coplanar lines when we take advanced math classes involving equations in vector and cartesian forms.
