It is possible for two planes to intersect in exactly one point. 3) When any two parallel lines are intersected by another line called a transversal, many pairs of angles are formed. (b) Two lines perpendicular to a third line are parallel. a. True or False? In a plane, if two lines are perpendicular to the same line, the two lines are parallel. By definition parallel lines are lines in a plane which do not meet, that means, they have to be coplanar. If two lines do not intersect then they are parallel. Explain. True or False?
