    let vertices's are A,B,C,D then let D is (a,b) then find mid point of AD and BC that is diagonals which are same in case of square compare and find value of a and b.

    mid point of AD is ((a+3)/2,(b+3)/2) and mid point of BC is ((-1-1)/2, (-1+3)/2) that is (-1,1) which is equal to (a+3)/2=-1 and (b+3)/2=1 solve it

    I made mistake, it is (-1,-1) not (-1,1) hence the answer is (3,-1)
