PROPERTIES OF PARALLELOGRAM A parallelogram is a four-sided flat shape whose opposite sides are both equal and parallel. Parallelogram has a special property of opposite sides being parallel and opposite angles being equal. A parallelogram is a quadrilateral, in which diagonals bisect each other.  # Finding area of Parallelogram using determinants. - YouTube
