and {tex}ar∆ABC=ar∆PQR{/tex}

To prove: {tex}∆ABC\cong∆PQR{/tex}
Proof: {tex}∆ABC\sim∆PQR{/tex} 
Also {tex}\operatorname { ar } ( \Delta A B C ) = \operatorname { ar } ( \Delta P Q R ){/tex} (given)
or, {tex}\frac { \operatorname { ar } ( \Delta A B C ) } { \operatorname { ar } ( \Delta P Q R ) } = 1{/tex}
Or {tex}\frac{AB^2}{PQ^2}=\frac{BC^2}{QR^2}=\frac{CA^2}{RP^2}=1{/tex}
Or {tex}\frac{AB}{PQ}=\frac{BC}{QR}=\frac{CA}{RP}=1{/tex}
Hence we get that
Hence {tex}∆ABC\cong ∆PQR{/tex}
