3 triangles that do not overlap are shown on the coordinate grid. these coordinates of all verticals are integers

The diagram can be drawn as,
In triangle PQR and PST
[tex]\begin{gathered} \angle QPR=\angle TPS(V.O.A) \\ \frac{QP}{PS}=\frac{9}{3}=3 \\ \frac{RP}{PT}^{}=\frac{6}{2}=3 \\ \frac{QP}{PS}=\frac{RP}{PT} \end{gathered}[/tex]Thus, from SAS,
[tex]\Delta STP\approx\Delta QRP[/tex]Thus, option (A) is the correct solution.
