\(\triangle PQM\cong\triangle PRM\) | Side-Side-Side Triangle Congruence Postulate |
Simple;
PQR is an isosceles triangle, and Q and P are reflected over the one line of symmetry, which happens to be PM if M is the midpoint of PR.
Yes, you are right that the isosceles triangle theorem would end this problem in one step.
