उत्तर
- In a parallelogram, opposite sides are equal in length.
AD = BC - In a parallelogram, opposite angles are equal in measure.
∠DCB = ∠DAB - In a parallelogram, diagonals bisect each other.
Hence, OC = OA - In a parallelogram, adjacent angles are supplementary to each other.
Hence, m∠DAB + m∠CDA =180°
