Answer :
Answer:
ΔQPS and ΔQRS are proven congurent triangles by SAS postulate only .
Step-by-step explanation:
As given the figure in the question .
In the ΔQPS and ΔQRS .
(1) QP = QR
(2) ∠PQS = ∠RQS
(3) QS = QS
Thus by using the SAS congurence property .
ΔQPS ≅ ΔQRS
Therefore ΔQPS and ΔQRS are proven congurent triangles by SAS postulate only .
your answer should be SAS only because you are sharing Two sides and 1 angle
