Answer:
R
Step-by-step explanation:
Apply the knowledge of CPCTC (corresponding parts of congruent triangles are congruent) to this
C and R are written last, and order is important, because they are congruent
[tex]\Delta ABC\cong\Delta PQR\\\\\begin{array}{ccc}\Delta&\to&\Delta\\A&\to&P\\B&\to&Q\\C&\to&R\end{array}\\\\\text{Therefore}\ \angle C\cong\angle R[/tex]
