Question

If $△ABC\sim △DEF,$
then, the side of $△DEF$ that corresponds to the side AB of $△ABC$ is ______.

• A. DE
• B. EF
• C. FD
• D. None of the above

Answer 1

The correct option is A DE


If $△ABC\sim △DEF$
Then, corresponding sides are in proportion.
$\Rightarrow \frac{AB}{DE}=\frac{BC}{EF}=\frac{CA}{FD}$

So, side DE of triangle DEF corresponds to side AB of triangle ABC.
