Question

AABC ~ APQR. In AABC, AB = 5.1 cm. ZB = 40°, BC = 4.8 cm,
AC/PR=4/7,construct AABC and APOR
​

Answer 1

Answer:

In ΔABC and ΔPQR

AB=PQ

And BC=QR

CB And RQ extended  to X and Y

∠ABX=∠PQY

∠ABC=180o−∠ABX=180o∠PQY

∠PQR=180o−∠PQY=∠ABC

We get in both triangles 

AB=PQ

BC=QR

And ∠ABC=∠PQR

Then both triangle are congruent

i.e. ΔABC=ΔPQR
