Question

if <1 cong <2 which lines are parallel?

By which theorem??
a. if 2 lines are cut by a transversal such that 2 int. angles on the same side of the transversal are supp. the lines are parallel
b. alternate int. angles---->parallel lines

Answer 1

@jim_thompson5910 please help

Answer 2

you're only given two answer choices?

Answer 3

no but i crossed out the other answers out since i didn't think they were correct

Answer 4

oh ok, well the idea is this

if the alternate interior angles are congruent, then the two lines are parallel

Answer 5

it's the converse of the alternate interior angles theorem

Answer 6

ok so the solution would be b

Answer 7

yeah it looks it

Answer 8

thanks:)
