Answer:

mark me as brainly

a and b are parallel

Answer 2

Step-by-step explanation:

Angle 1=Angle 2  (vertically opposite angles)

angle 1 + 130 = 180  ( Linear Pair)

angle 1 = 50 = angle 2

Angle 3 = Angle 4  ( Vertically Opposite Angles)

angle 3 + 50=180  (Linear Pair)

angle 3 = 130 = angle 4
