The points P and S are on the same side of the line segment QR, such that ∠PQR = 90°, ∠SRQ = 90° and PQ = SR. Select the correct statement.

∠PQR = 90°

∠SRQ = 90°

PQ = SR

Points P and S are on the same side of the line segment QR.

Concept Used:  

SAS (Side -Angle-Side) Property:

According to this rule, if the two side and angle between them of a triangle are respectively equal to the two sides and angle of another triangle, then the two triangles are congruent. 

Solution: 

In $$\triangle PQR \quad \text{and}\quad \triangle SRQ$$ 

∠PQR = ∠SRQ = 90°

PQ = SR

QR = QR ( common) 

Two side and angle between them is equal 

then, $$\triangle PQR \quad \cong\quad \triangle SRQ$$ , by SAS congruency​
