WebJan 4, 2024 · As we have already proven, the opposite sides of a parallelogram are equal in size, giving us our needed side. Once we show that ΔAOD and ΔCOB are congruent, we will have the proof needed, not just for AO=OC, but for both diagonals, since BO and OD are also corresponding sides of these same congruent triangles. Proof WebID: A 2 6 ANS: Because diagonals NR and BO bisect each other, NX ≅RX and BX ≅OX.∠BXN and ∠OXR are congruent vertical angles. Therefore BNX ≅ ORX by SAS.
