Triangle A is transformed by the combined transformation of a rotation of \(180^\circ\) about the point \((-2, 0)\) followed by a translation with vector \(\begin{pmatrix} -3 \\ 2 \end{pmatrix}\)
One point on triangle A is invariant under the combined transformation.
Find the coordinates of this point. (2)
