By that description, all the sides are parallel and have 90 degree angles... But the sides aren't necessarily the same length. So a square is one example, but you could also have a long rectangle. apex=False
it depends on its shape. if it is a parallelogram, then its true. but if it is a trapezoid, then eventually not.
