Question

-_- how to solve this

Answer 1

gow can i prove that these lines are parallel

Answer 2

well, 107 + 73 is 180. because of the corresponding angles theorem (which states that corresponding angles in a transversal are congruent), you know that the two lines are parallel.

Answer 3

they're parallel because 107 + 73 = 180 ? i can tell by just looking but the explanation part kills me lol

Answer 4

they are not parraallel

Answer 5

they would be parallel if both of the angles were equal.......

Answer 6

please explain , lol

Answer 7

oh thanks

Answer 8

a and b are corresponding angles and two lines can be parallel if corresponding angles are equal not when sum is 180
if the case was for co interior angles, their sum 180 make them parallel
