Answer 2

Answer:

(6)

1) Yes triangle PQR is congruent to triangle PSR by (SAS Congruency)

2) yes QR=SR( by corresponding sides of congruent triangles)

(7)

1)ΔQSR≅ΔRTQ(SAS Congruency)

2)∠PQR=∠PRQ(YES)

Step-by-step explanation:

For the congruency to be SAS that is Side Angle Side we need to prove that there are two sides and the angle between those sides is equal in both  the triangles then only we will be able to solve this question and prove this

so here,

PQ=PS (Given)

∠1=∠2 (Given)

PR=PR (Common side)

∴ Both triangle are congruent by Side Angle Side congruency i.e. ΔPQR≅ΔPSR

⇒QR=SR(CPCT/ corresponding sides of congruent triangles)

(7)

For the congruency to be SAS that is Side Angle Side we need to prove that there are two sides and the angle between those sides is equal in both  the triangles then only we will be able to solve this question and prove this

so here,

TR=SQ (Given)

∠QTR=∠QSR (Given)

QR=QR (Common side)

∴ Both triangle are congruent by Side Angle Side congruency i.e. ΔQSR≅ΔRTQ (i)

∠SQR=∠TRQ(CPCT)

⇒ΔPQS≅ΔPTR

∠PQS=∠PRT(CPCT)

On adding above two equations we get,

∠PQR=∠PRQ (ii)
