Given: a ∥ b and ∠1 ≅ ∠3 prove: e ∥ f we know that angle 1 is congruent to angle 3 and that line a is parallel to line b because they are given. we see that by the alternate exterior angles theorem. therefore, angle 2 is congruent to angle 3 by the transitive property. so, we can conclude that lines e and f are parallel by the converse alternate exterior angles theorem. which information is missing in the paragraph proof? ∠2 ≅ ∠4 ∠1 ≅ ∠2 ∠2 ≅ ∠3 ∠1 ≅ ∠4
