Answer:
QTS & TQS
Explanation:
so as PQ=QT is given & QS is an common side, you can take the triangle PQS & TQS as isosceles triangles.
so then the angles PSQ=QST becoz the angles opposite to equal sides of an isosceles triangle are also equal in measures.
PQ=QT (given)
QS = common side
PSQ=QST (the angles opposite to equal sides of an isosceles triangle are also equal in measures.)
Therefore PQS is congruent to QTS (S.S.A)
