Draw E C .
Triangle C D E is half of parallelogram A B C D because they have a common side and the third point is on the opposite side.
Triangle C D E is also half of parallelogram E F G D because they have a common side and the third point is on the opposite side.
Therefore the parallelograms have the same area.
