You have to check the slopes of two sides that intersect each other to see if the slopes are negative reciprocals of each other, which proves perpendicular for a rectangle to exist. If not perpendicular, then it is a parallelogram only.
These turn out to be slopes of 2/3 and -3/2 for perpendicular,
and the same of another pair of slopes.
So the figure is a rectangle.
