Answer:
Step-by-step explanation:
We know that ABCD is a parallelogram whose diagonals intersect each other at O
Consider △AOE and △COF
We know that ∠CAE and ∠DCA are alternate interior angles
⟹∠CAE=∠DCA
From the figure we know that the diagonals are equal and bisect each other
⟹AO=CO
We know that ∠AOE and ∠COF are vertically opposite angles
⟹∠AOE=∠COF
By ASA congruence criterion
△AOE≅COF
⟹OE=OF (By C.P.C.T
