Best ResponseYou've already chosen the best response.1Now that you know it's a parallelogram, you need to find out if it is also a rectangle. Find the slopes of two adjacent sides. If their product is 1, the sides are perpendicular, and it is a rectangle, if not, then it's just a parallelogram. dw:1388333794191:dw
