Best ResponseYou've already chosen the best response.0Ah, okay. Well, you'll have to learn how to classify the angles. Like, if we just ignored what the question was asking, we would have to know what all the angles are relative to each other. Like step 2 said, angles 2 and 3 are vertical angles. 1 and 4 are also vertical angles, as well as 5 and 8, 6 and 7. But yes, they are alternate interior angles, so thats the theorem thats needed here :) 4 and 5 are also alternate interior angles. This problem doesnt need that, but you should be able to get that. So yeah, try and get used to being able to classify angles. Should be able to name pairs of alternate exterior, adjacent, corresponding, etc. But yes, 3 and 6 are alternate interior angles, so thats the step in the proof :)
