Given:
[tex]\begin{gathered} \angle S\cong\angle W(Angle) \\ SR=WX(\text{Side)} \\ \angle R\cong\angle S(Angle) \end{gathered}[/tex]
To complete the statement:
By using the ASA similarity,
[tex]\Delta\text{RST}\cong\Delta\text{XWY}[/tex]
Hence, the answers are,
[tex]\begin{gathered} \Delta\text{RST}\cong\Delta\text{XWY} \\ Reasoning\colon ASA\text{ similarity} \end{gathered}[/tex]
