    Which statement should Jamal use to prove that lines a and b are parallel? ∠3 = 120° ∠7 = 120° ∠2 = 60° ∠4 = 60°

    The second answer is correct. Angles on a straight line add up to 180 so Angle 2 = 60 Alternate angles also equal 180 so Angle 4 = 60 and Angle 3 = 120 Now you need to find a corresponding angle on the other line and Angle 7 is the only option you're given so if that equals 120, the rule of corresponding angles means that the lines are parallel. Hope this helps! :)

    Thank you so much. That was the answer I got but I did not completely understand why! Thanks. Not to be rude but is there any way you could check out the question before this and help me out? It's a closed question.

    I'm pretty sure they're both correct, they just use a different angle. One uses Angles 1 and 3 and 4 and 3 The other uses 1 and 2 and 3 and 2
