Question

name the marked angle in 2 different ways. answer attempt 1 out of 2

Explanation:

Step1: Use vertex - based naming

An angle can be named by its vertex when there is only one angle at that vertex. Here the vertex is E, so one way is $\angle E$.

Step2: Use three - point naming

An angle can be named using three points where the middle point is the vertex. For the marked angle, we can name it as $\angle DEF$ (the order of the non - vertex points can be reversed too, like $\angle FED$).

Answer:

$\angle E$, $\angle DEF$
