yes

Answer 3

what statements are given to you?

meaning answers?

Answer 5

yes, what are your possible answers?

Answer 6

let me get them

Answer 7

Notice how there are right angle markers at angles J and M

Answer 8

yes

Answer 9

So these angles are 90 degrees. They add to 90+90 = 180

Because they are supplementary, this means that JK || ML. They are parallel by the converse of the same side interior angle theorem (which says that if two same side interior angles are supplementary, then the lines are parallel)
