03.01 LC) Danny draws a transversal, t, on two parallel lines AB and CD, as shown below: Two parallel lines are shown cut by a transversal labeled t. 1, 2, 7 and 8 are marked clockwise as exterior angles. 4, 3, 6, an He makes the following table to prove that the alternate interior angles are equal: Statement Justification angle 2 = angle 6 ? angle 2 = angle 4 Vertical angles are congruent. angle 4 = angle 6 transitive property of equality, angle 2 = angle 6, angle 2 = angle 4, therefore angle 4 = angle 6 Which is the missing justification? (6 points) Corresponding angles formed by a transversal on parallel lines are supplementary. Corresponding angles formed by a transversal on parallel lines are congruent. Co-interior angles formed by a transversal on parallel lines are congruent. Co-exterior angles formed by a transversal on parallel lines are congruent
