Answer 2

Given, one angle of ||gm is 50° = A

angle A = angle C (opp angles of ||gm are equal)

Therefore, angle C = 50°

Angle B + angle C = 180° (angles on the same side of transversal)

B + 50 = 180

Angle B = 130°

Angle B = Angle D(opp Angles of ||gm)

Angle D= 130°

Angle A= 50°

Angle B= 130°

Angle C= 50°

Angle D= 130°

Hence, proved
