Question 6660: Hi,
I have tried this but am new to it and not sure.
Question is: The coordinates of three vertices of a rectangle are (-2,1), (0,-1), and (3,2). First part - What is the fourth vertex? I said (5,0). Is that correct? Second part - What is the length of the diagonal of the rectangle? I said the rise is 2 and the run is -2, making the slope -1, is that the length? Answer by ichudov(499) (Show Source):
