Step-by-step explanation:
Given: Quadrilateral PQRS is a rectangle.
To prove: PR = QS
Proof: 1. Quadrilateral PQRS is a rectangle(Given).
2. Rectangle PQRS is a parallelogram (Definition of a rectangle).
3. QP ≅ RS QR ≅ PS (Opposite angles of parallelogram are equal).
4. m∠QPS = m∠RSP = 90° (definition of a rectangle)
5. Δ PQS ≅ ΔSRP (SAS criterion for congruence)
6. PR ≅ QS (Corresponding sides of congruent triangles are congruent).
7. PR = QS (Congruent line segments have equal measures).
