ΔABC ≈ΔDEF⇒ $\frac{AB}{DE} = \frac{BC}{EF} = \frac{AC}{DF} = \frac{1}{2}$

$\frac{AB}{DE} = \frac{1}{2}$⇒  \frac{4}{de} =  \frac{1}{2} [/text] ⇒ DE=8

 \frac{BC}{EF} =  \frac{1}{2} [/tex] ⇒  \frac{6}{EF} =  \frac{1}{2} [/tex] ⇒ EF =5

 \frac{AC}{DF} =  \frac{1}{2} {/tex] ⇒  \frac{5}{DF} =  \frac{1}{2} [/tex] ⇒ DF=5
