Question

Two lines on the graph are cut by a transversal. Which angles must be congruent for the lines to be parallel?

A) ∠1 and ∠4
B) ∠1 and ∠8
C) ∠2 and ∠4

Answer 1

I believe ur answer is < 1 = < 8...because alternate exterior angles are congruent.....this has to do with transversals and parallel lines

reason it is not < 1 = < 4 is because vertical angles are always congruent....this has nothing to do with a transversal and parallel lines. And < 2 and < 4 are not congruent
