Question

pls solve the problem as fast as possible

Answer 1

Step-by-step explanation:

Consider lines AB and CD

∠ABC=∠BCD=65°

Since the interior opposite angles are equal these lines are parallel

AB ||CD. (1)

Consider lines EF and CD

∠FEC+∠ECD=145+35=180°

Since the co interior angles are supplementary these lines are parallel

CD ||EF. (2)

By (1)&(2)

AB ||EF

Hence proved
