Question

Examine whether AB and CD are parallel in each of the following cases. Write proper reason.

( kindly note that the picture is above <(￣︶￣)↗)
(i) ∠b = 80°, ∠y = 80°
(ii) ∠b = 70°, ∠z = 70°
(iii) ∠a = 40°, ∠y = 40°
(iv) ∠b = 100°, ∠x = 80°
(v) ∠c = 65° , ∠x = 65°
(vi) ∠a = 42° , ∠x = 42°

please help me with this question​

Answer 1

Step-by-step explanation:

b=80°,y=80°(corresponding angle)

a=70°,z=70°(alternate angle)

a=40°,z=40°{alternate)

x=80°,a=80°[corresponding]

(v) is correct.

(VI) is correct.
