Two lines AB and CD intersect at O such that BC is equal and parallel to AD. Prove that the lines AB and CD bisect at O.
Given that lines AB and CD Intersect at O.
Such that BC ∥ AD and BC = AD ... (i)
We have to prove that AB and CD bisect at O.
To prove this first we have to prove that ΔAOD ≅ ΔBOC
