Answer:
Quadrilateral DEFG is not a rectangle because it has no right angles.
Step-by-step explanation:
Plotting the coordinate points, we have a quadrilateral but not a rectangle. Looking at the points and the angles formed, we see that there do not have any right angle. In addition to this, whenever we have a rectangle we have common coordinates, like the second picture.
