determine whether the triangles are similar by aa-, sss-, sas-, or not similar.

Explanation:

Step1: Identify vertical angles

Vertical angles $\angle SEF$ and $\angle GED$ are equal.

Step2: Calculate side ratios

First ratio: $\frac{SE}{GE} = \frac{20}{15} = \frac{4}{3}$
Second ratio: $\frac{FE}{DE} = \frac{40}{18} = \frac{20}{9}$

Step3: Compare ratios

$\frac{4}{3}
eq \frac{20}{9}$, so the sides around the equal angle are not proportional.

Answer:

Not Similar
