Question

which angle refers to the same angle as ∠def? choose 1 answer

Explanation:

Step1: Recall angle - naming convention

An angle $\angle DEF$ is named with the vertex letter $E$ in the middle. The angle is formed by the rays $\overrightarrow{ED}$ and $\overrightarrow{EF}$.

Step2: Check each option

We need to find the option where the vertex is the middle - named point and the rays forming the angle are equivalent in direction and position relative to the vertex as in $\angle DEF$.

Answer:

(Without seeing the actual content of options A, B, C, D, we can't give the specific correct option. But the general approach is to look for the angle with the vertex in the middle and rays in the same relative orientation as in $\angle DEF$.)
