4. Two mark example problems II

1. Is \(\Delta ABC \sim \Delta PQR\)?

 

 

 

 

 

$\frac{\mathit{PQ}}{\mathit{AB}}$ ≠= $\frac{\mathit{QR}}{\mathit{BC}}$

 

$\mathrm{\Delta }\mathit{ABC}$ similar tonot similar to $\mathrm{\Delta }\mathit{PQR}$.

 

2. If \(\Delta ABC\) is similar to \(DEF\) such that \(BC = 3 \ cm\), \(EF = 4 \ cm\) and area of \(\Delta ABC = 54 \ cm^2\). Find the area of \(\Delta DEF\).

 

 

The area of \(\Delta DEF =\) \(cm^2\).
