The rectangle is slanted with respect to the axes.
Make a sketch to see if the corners are in order.
You can use the graphing tool desmos.com to help you plot.
From the plot, it looks like the three points A, B and C do not form any right-angle, so there must be a typo with the coordinates.
Please check the information provided.

find two perpendicular lines from the three points by finding the slopes between the three pairs
... that is one corner
... you are looking for the opposite corner
... use the slopes from the ends of the sides to find the missing point
this should be very simple by using graph paper
