Consider the two triangles in the diagram below:
Two triangles, $\triangle PQR$△PQR and $\triangle ABC$△ABC, 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 angle at vertex $R$R, $\angle PRQ$∠PRQ, is marked with a small yellow square. The side $PQ$PQ measures $7$7 units and is opposite $\angle PRQ$∠PRQ at vertex $R$R. The side $PR$PR measures $4$4 units and is opposite $\angle PQR$∠PQR at vertex $Q$Q. The side $RQ$RQ is unlabeled and is opposite $\angle RPQ$∠RPQ at vertex $P$P. The triangle below is $\triangle ABC$△ABC labeled with vertices $A$A, $B$B, and $C$C. The angle at vertex $C$C, $\angle ACB$∠ACB, is marked with a small yellow square. The side $AB$AB measures $7$7 units and is opposite $\angle ACB$∠ACB at vertex $C$C. The side $AC$AC measures $4$4 units and is opposite $\angle ABC$∠ABC at vertex $B$B. The side $BC$BC is unlabeled and is opposite $\angle BAC$∠BAC at vertex $A$A.
