The points \(A(28,40)\), \(B(-8,20)\) and \(C(12,-16)\) in order are the vertices of a right-angled triangle. The right-angled triangle satisfies the . Verify this and calculate the side of the triangle using the distance formula.
The sides of the right-angled triangle:
\(AB =\) .
\(BC =\) .
\(AC =\) .
