parallelogram proofs answers hat the vectors AB and DC are equal and parallel. Step 2: Given a + c = b + d, rearranged as: b - a = c - d but since a + c = b + d, subtracting a + c from both sides yields: 0 = (b - a) + (d - c) which rearranged as: b - a = -(d - c) This suggests that AB is parallel and equal in len Jul 5, 2026 Read more →
