Answer:
Therefore, the quadrilateral PQRS is a kite.
Step-by-step explanation:
The given information defines a kite, as the diagonals of a kite are equal in length and bisect each other at right angles. The length of diagonal PQ is 8 cm, and the length of diagonal SR is 8 cm. The perpendicular bisector of PR intersects PR at T such that PT = RT = 9 cm.
