question 3 of 10
which of the following describe an angle with a vertex at e?
check all that apply.
a. ∠def
b. ∠dfe
c. ∠fed
d. ∠efd

Explanation:

Step1: Recall angle - naming convention

An angle is named with the vertex letter in the middle.

Step2: Analyze each option

For $\angle DEF$, the vertex is $E$. For $\angle FED$, the vertex is also $E$. While for $\angle DFE$, the vertex is $F$ and for $\angle EFD$, the vertex is $F$.

Answer:

A. $\angle DEF$, C. $\angle FED$
