Answer:

Step-by-step explanation:

∠FEC = 145°

∠ECD = 35°

so,  ∠FEC + ∠ECD = 145 + 35 = 180°

so, EF ║ CD  ( Sum of interior angles on the same side of a transversal = 180°)  

∠ABC = 65°

∠BCD = 65°

so,  ∠ABC = ∠BCD = 65°

so, AB ║ CD (Alternate interior angle is equal)

now, AB ║ CD and EF ║ CD,  AB ║ EF ║ CD

Hence prove,  AB ║ EF.
