Question

Select the appropriate alternative.
In ∆ABC and ∆PQR, in a one to one correspondence \[\frac{AB}{QR} = \frac{BC}{PR} = \frac{CA}{PQ}\] 

Options

• ∆PQR ~ ∆ABC 

• ∆PQR ~ ∆CAB 

• ∆CBA ~ ∆PQR 

• ∆BCA ~ ∆PQR

Answer 1

\[\frac{AB}{QR} = \frac{BC}{PR} = \frac{CA}{PQ}\] 

By SSS test of similarity
 ∆PQR ~ ∆CAB
Hence, the correct option is ∆PQR ~ ∆CAB.
