Question

two triangles are congruent. 7. In AABC and APQR, AB = PQ, BC=QR. CB and RQ are extended to X and Y respectively and ZABX = ZPQY. Prove ( that AABC APQR. [CBSE SP 2010] Х​

Answer 1

In ΔABC and ΔPQR

AB=PQ

And BC=QR

CB And RQ extended to X and Y

∠ABX=∠PQY

∠ABC=180

o

−∠ABX=180

o

∠PQY

∠PQR=180

o

−∠PQY=∠ABC

We get in both triangles

AB=PQ

BC=QR

And ∠ABC=∠PQR

Then both triangle are congruent

i.e. ΔABC=ΔPQR
