In parallelogram ABCD, E is the mid-point of AD and F is the mid-point of BC. Prove that BFDE is a parallelogram.

KnowledgeBoat · Accepted Answer

Given: Parallelogram ABCD in which E and F are mid - points of AD and BC. To prove: BFDE is a parallelogram Proof: E is the mid-point of AD. DE = AD Also, F is the mid-point of BC. BF = BC But as we know opposite sides of parallelogram are equal. So, AD = BC Therefore, DE = BF And, also AD is parallel to BC. So, DE is parallel to BF. When DE = BF and DE is parallel to BF. (opposite sides are equal and parallel to each other) Hence, BFDE is a parallelogram.
