In the diagram, \(AB = 13\text{ cm}\), \(BC = 84\text{ cm}\) and \(AC = 85\text{ cm}\).

Show that line \(AB\) is perpendicular to line \(BC\).

\(P\), \(Q\), \(R\) and \(S\) are four points lying in the same plane.

\(PQR\) lies on the same straight line. \(PR\) is perpendicular to \(QS\).
\(PS = 12\text{ cm}\), \(QS = 7\text{ cm}\) and angle \(QSR = 67^\circ\).
