Michael and Derrick each completed a separate proof to show that corresponding angles AKG and ELK are congruent. Who completed the proof incorrectly? Explain. Line AB is parallel to EF, transversal GJ crosses line AB at K and crosses line EF at L. Michael's Proof Statement Justification 1. line AB ∥ line EF with transversal segment GJ 1. Given 2. angle AKG is congruent to angle AKL 2. Vertical Angles Theorem 3. angle BKL is congruent to angle ELK 3. Alternate Interior Angles Theorem 4. angle AKG is congruent to angle ELK 4. Transitive Property Derrick's Proof Statement Justification 1. line AB ∥ line EF with transversal segment GJ 1. Given 2. angle AKG is congruent to angle BKL 2. Vertical Angles Theorem 3. angle BKL is congruent to angle ELK 3. Alternate Interior Angles Theorem 4. angle AKG is congruent to angle ELK 4. Transitive Property
