Parallelogram PQRS has diagonal PR drawn.
(i) A student writes the congruence statement △PQR≅△SRP. Identify the pair of corresponding parts the student has matched in this statement.
(ii) Explain, with reasons based on the properties of a parallelogram, whether the student’s claim of congruence is valid.
(iii) If the claim is valid, name the congruence criterion satisfied. If it is not valid, write the correct congruence statement and justify your answer.
