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
