Let $A(x, y, z)$ be a point in $xy$-plane, which is equidistant from three points $(0, 3, 2), (2, 0, 3)$ and $(0, 0, 1)$. Let $B = (1, 4, -1)$ and $C = (2, 0, -2)$. Then among the statements (S1) : $\triangle ABC$ is an isosceles right angled triangle, and (S2) : the area of $\triangle ABC$ is $\frac{9\sqrt{2}}{2}$
