Answer 1

Answer:

angle 1 +100=180   (linear pair)

angle 1=80

angle 2 =100 (corresponding)

angle 3 = angle 1  = 80 (corresponding)

angle 2 = angle 4 = 100 (alternative interior angles)

angle 5 = angle 3 = 80 (alternative interior angles)

angle 5 = angle 7 = 80 (corresponding)

angle 6 = angle 4 = 100 (corresponding)
