Which two theorems would justify that m∠4 = m∠6, given that m∠5 = m∠6 in the diagram below? vertical angles theorem, consecutive interior angles theorem
corresponding angles theorem, angle addition theorem
right angles theorem, exterior angles theorem
vertical angles theorem, alternate interior angles theorem

D) vertical angles theorem, alternate interior angles theorem

Angle 5 = Angle 6 by the alternate interior angles theorem

Angle 5 = angle 4 by the vertical angles theorem

By the transitive property, we can then say angle 4 = angle 6. These angles are also corresponding angles.

We won't use the angle addition theorem or the right angles theorem.
