Question

Which lines are parallel if m1 + m2 = 180? Justify your answer.

Answer 1

(A) j || k by the converse of the same-side interior angle Theorem is your answer

Note that " j || k" means that line j & k are parallel (True)

Note that both ∠1 & ∠2 are on the same side, and that they are located inside the parallelogram produced by the transversal lines (Same Side - Interior Angle Theorem)

Therefore, (A) is your answer
