Answer:

[tex]\frac{PQR}{SQR}[/tex]

Step-by-step explanation:

An isosceles triangle has two equal sides and the two opposite angles to the sides to be equal.

Given that; RP = RS, RQ and PS are common,

RP = SQ (opposite sides of parallelogram RPQS)

PQ = RS (opposite sides of parallelogram RPQS)

ΔRPS = ΔQPS (congruence property)

Thus comparing triangles PQR and SQR,

[tex]\frac{PQ}{SQ}[/tex] = [tex]\frac{PR}{SR}[/tex] (similarity property)

<PRS = <PRQ + <SRQ (bisection of included <PRS)

<PQS = <PQR + <SQR (similatity property to <PRS)

[tex]\frac{PRQ}{SRQ}[/tex]  = [tex]\frac{SQR}{PQR}[/tex] (congruence property)

But, SRQ = PQR

So that;

       [tex]\frac{PRQ}{SQR}[/tex]

Therefore by Side-Angle-Side (SAS), the required additional fact is:  [tex]\frac{PRQ}{SQR}[/tex]

Answer:

PQR=SQR
