$\"\"$

Observe the figures:

Consider the first triangle is $\"\"$ and second triangle is $\"\"$ .

$\"\"$ measures are $\"\"$ and $\"\"$ .

If $\"\"$ and $\"\"$ are similar, then measures of their corresponding sides are proportional.

$\"\"$

Therefore, $\"\"$ and $\"\"$ sides are not proportional.

$\"\"$

No; the sides are not proportional.
