b

anonymous · Answer

we know nothing about line g and the two angles are alternate interior

anonymous · Answer

i had my answer on b thats so crazy i wasn't sure though if it was postulate or theorem

anonymous · Answer

can you explain those to me please ?

anonymous · Answer

same side interior angles would be like 2 and the angle to the left of 1  

1 and 2 are not on the same side  they are alternate interior angles

ohh ok i get it a little more now
