E and F are points on diagonal AC of a parallelogram ABCD such that AE = CF. Show that BFDE is a parallelogram.
Given : ABCD is a parallelogram and AE = CF
To prove: OE = OF
Proof: Join BD and CA
Here and [ABCD is parallelogram]
…..(1)
And …..(2) {given}
{by subtracting 2 from 1}
Hence, BFDE is a parallelogram.
