1. The shape cannot be a rectangle or a square because they have right angles.

2. It cannot be a hexagon because a hexagon has 6 sides.

3. It cannot be a rhombus because all sides of a rhombus are of equal length.

4. The only quadrilateral with parallel opposite sides and different lengths is a parallelogram.
