Two triangles PQR and STU are drawn such that ∠PQR=∠STU, ∠PRQ=∠SUT and PQ=ST. Answer the following questions.
(a) Name the side that lies between the two equal angles in each triangle.
(b) State with reason whether the given information is sufficient to conclude that △PQR≅△STU. Mention the congruence criterion you use.
(c) If the triangles are congruent, list all pairs of corresponding equal sides and equal angles.
(d) Explain whether the equality QR=TU follows from the information provided. Give justification for your answer.
