Select all the true statements. If vertical angles are congruent, then two lines cut by a transversal are parallel. If two parallel lines are cut by a transversal, then corresponding angles are congruent. If two parallel lines are cut by a transversal, then alternate interior angles are congruent. Points on a perpendicular bisector of a line segment are equidistant from the segment's endpoints. Points on a perpendicular bisector of a line segment are not equidistant from the segment's endpoints.
