The points have the following coordinates:

A(3,-2)

B(p,3)

C(6,2)

D(q,r)

The figure ABCD is a rhombus. Find the values of p, q and r.

Even though I used the midpoint formula and the distance formula, I could not deduce the values of p and q.

with the midpoint formula, i did get the value for r (-3).
