Parallelogram in a Quadrilateral (grid version)

There are a series of quadrilaterals presented on a grid. The initial task is to form the shape derived by joining the midpoints of each side. The resulting quadrilateral is in each case a parallelogram. Not only that but each parallelogram is similar. The second part of the investigation involves proving that the area of the parallelogram is the same in each case.
