Question

$\text{If in}△CAB\text{and}△FED,$

$\frac{AB}{EF}=\frac{BC}{FD}=\frac{AC}{ED}$,

$\text{then which of the following is true?}$

Answer 1

If in two triangles, the corresponding sides are in the same ratio, then their corresponding angles are equal.

$\text{Here, in}△CAB\text{and}△FED,$

$\frac{AB}{EF}=\frac{BC}{FD}=\frac{AC}{ED}\text{(given)}$

$\therefore △ABC\sim △EFD.$
