AB = sqr root (53)^2 + (2+5)^2 = sqr root 13 BC = sqr root(105)^2 + (4+2)^2= sqr root 29 CD= sqr root(810)^2 + ((7+4)^2 = sqr root 13 DA = sqr root(38)^2 + (5+7)^2 = sqr root 29 ABCD is paralellogram

Now 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
