What are the missing statement and reason in step 2 of the proof? A.
Statement: AB ≅ CD, BC ≅ AD
Reason: given
B.
Statement: ΔABC ≅ ΔCDA
Reason: SSS criterion for congruence
C.
Statement: ∠BAC ≅ ∠ACD
Reason: Alternate Interior Angles Theorem
D.
Statement: ∠ABC ≅ ∠BCD, ∠BAD ≅ ∠ADC
Reason: For parallel lines cut by a transversal, corresponding angles are congruent.
E.
Statement: AB ∥ CD, BC ∥ AD
Reason: definition of a parallelogram
