# If $\Delta ABC \approx \Delta EDF \;and\; \Delta ABC$ not similar to $\Delta DEF$ then which of the following is not true?

$\begin{array}{1 1} BC . DE = AB .EF.\\ BC .EF = AC .FD. \\ AB .EF = AC . DE. \\ BC . DE = AB .FD. \end{array}$

If $\Delta ABC \approx \Delta EDF$ and $\Delta ABC \approx \Delta EDF$ and $\Delta ABC$ is not similar to $\Delta DEF$ ,then $BC. DE = AB .EF⇒BCEF= \large\frac{AB}{DE} =\frac{BC}{EF}$ Here according to given condition,
$BC. DE \neq AB .EF$
