First we need to find lengths of the sides using distance formula we get
OA = 3 units = √(0 - 0)2 + (3 - 0)2 
AB = 4 units = √(4 - 4)2 + (3 - 0)2 
BC = 3 units = √(0 - 3)2 + (4 - 4)2 
OC = 4 units = √(4 - 0)2 + (0 - 0)2 
Hence, OABC is a rectangle.
 
 
NOTE : If you plot given points on the graph you will get rectangle.
