The points \(A(16, -6)\), \(B(-12, 2)\), \(C(-12,12)\) and \(D(16,4)\) in order are the vertices of a parallelogram. In the parallelogram, the opposite sides are equal. Calculate the side values of the parallelogram using the distance formula.
The sides of the parallelogram:
\(AB =\) .
\(BC =\) .
\(CD =\) .
\(AD =\) .
