Two polygons are similar if and only if their corresponding angles are congruent

and the measures of their corresponding sides are proportional.

From the figures $\"\"$ . $\"\"$

Now determine whether corresponding sides are proportional.

Find the ratios of the measures of the corresponding sides.

$\"\"$ $\"\"$

Since the ratios of the measures of the corresponding sides are not equal, and the

corresponding angles are congruent, so $\"\"$ . $\"\"$

The pairs of figures are similar. $\"\"$ .
