Which of the following correctly justifies statement 4 of the two-column proof? Lines JK and LM are intersected by transversal JL; the intersection of JK and JL creates angles 2, 4, 3, and 1 clockwise beginning at the top right; the intersection of LM and JL creates angles 6, 8, 7 and 5 clockwise beginning at the top right. Given: line JK is parallel to line LM Prove: ∠2 ≅ ∠7 Statement Justification 1. line JK is parallel to line LM 1. Given 2. ∠6 ≅ ∠7 2. 3. ∠2 ≅ ∠6 3. 4. ∠2 ≅ ∠7 4.
