In the diagram below , ^PQR = ^STR . Complete the statement PW = _

Given:
[tex]\Delta PQR\cong\Delta STR[/tex]From the figure shown,
It is clear by the similarity of triangles,
[tex]\frac{PQ}{TS}\cong\frac{QR}{TR}\cong\frac{PR}{RS}[/tex]Therefore, Line PQ is congruent to line TS
Hence,
[tex]PQ\cong TS[/tex]Thus, option C is correct.
