Expert Answer
Given: ABCD is a parallelogram and AE = CF ...(1)
To Prove: ED
BF
Proof:
Since the opposite sides of the parallelogram are equal.
AB = CD ... (2)
Subtract (1) from (2):
AB - AE = CD - CF
BE = DF ... (3)
Also, BE is parallel to DF, therefore BEDF is a parallelogram.
Thus ED is parallel to BF.
