Given: AB←→ || CD←→ , and ∠EIJ≅∠GJI (figure).

Prove: ∠IKL and ∠IJL are supplementary.

Answer 3

A) Statement: ∠IKL≅∠JLK
Reason: For parallel lines cut by a transversal, corresponding angles are congruent.

B) Statement: ∠IKL and ∠IKC are supplementary.
Reason: Linear Pair Theorem

C) Statement: ∠GJI≅∠JLK
Reason: For parallel lines cut by a transversal, corresponding angles are congruent.

D) Statement: ∠GJI and ∠IJL are supplementary.
Reason: Linear Pair Theorem
