Answer:
Step-by-step explanation:
A parallelogram is a family of quadrilateral which has its two opposite sides to be equal and parallel.
In the given parallelogram, the following proof can be deduced.
1. QS bisects RT: <RSQ ≅ <TQS Given
2. RV ≅ TV Definition of a bisector
3. <SRQ + < RQT = [tex]180^{o}[/tex] Definition of supplementary angles
4. <RQS ≅ <QST Definition of alternate angles
5. <RVT ≅ <QVT Vertically opposite angles
6. <QRS ≅ <STQ Opposite angles are congruent
7. QRST is a parallelogram Proofed
