(b) Write the inverse of the given statement. A figure is a parallelogram if and only if it is a quadrilateral. If a figure is a parallelogram, then it is not a quadrilateral. If a figure is not a quadrilateral, then it is a parallelogram. If a figure is a quadrilateral, then it is a parallelogram. If a figure is not a parallelogram, then it is not a quadrilateral. If a figure is not a quadrilateral, then it is not a parallelogram.
