Given that $\triangle PQR$PQR$\cong$$\triangle STU$STU:

Two triangles, $\triangle PQR$PQR and$\triangle STU$STU, have their vertices marked with solid dots. The triangle above is $\triangle PQR$PQR, labeled with vertices $P$P, $Q$Q, and $R$R. The side $QR$QR is opposite $\angle QPR$QPR. The side $PQ$PQ is opposite $\angle PRQ$PRQ. The side $PR$PR is opposite $\angle PQR$PQR. The triangle below is $\triangle STU$STU, labeled with vertices $S$S, $T$T, and $U$U. The side $TU$TU is opposite $\angle TSU$TSU. The side $ST$ST is opposite $\angle SUT$SUT. The side $US$US is opposite $\angle STU$STU. Both $\angle PRQ$PRQ of $\triangle PQR$PQR and $\angle SUT$SUT of $\triangle STU$STU are marked with a yellow-shaded single arc. Both $\angle QPR$QPR of $\triangle PQR$PQR and $\angle TSU$TSU of $\triangle STU$STU are marked with a blue-shaded double arc.
