This video talks about sides and angle related Theorems of the parallelogram. The proof of each one of the theorems is also explained in the video. The theorems covered in this video are – In a parallelogram, the opposite sides are equal and its converse (If each pair of opposite sides of a quadrilateral are equal, then it is a parallelogram), If a pair of opposite sides of a quadrilateral is equal & parallel then it is a parallelogram, Opposite angles are equal in a parallelogram and its converse theorem (If each pair of opposite angles of a quadrilateral are equal, then it is a parallelogram).
