Inverse- If a quadrilateral is not a rectangle, then it is not a parallelogram. 

Contrapositive- If a quadrilateral is not a parallelogram, then it is not a rectangle. 

The inverse is false- there are non-rectangular parallelograms. The contrapositive is true- a rectangle will always be a parallelogram, so if a shape isn't a parallelogram, it cannot be a rectangle.
