Question

look at this angle:
name this angle:

Explanation:

Identify the vertex and points on the rays

The vertex of the angle is \(E\).
The points on the two rays forming the angle are \(D\) and \(F\).

Determine the standard three-letter names

An angle is named using three letters, with the vertex in the middle:
\(\angle DEF\) or \(\angle FED\).

Determine the single-letter name

Since there is no ambiguity at vertex \(E\), the angle can also be named by its vertex:
\(\angle E\).

Answer:

Look at this angle:
Name this angle: <blank>\(\angle DEF\)</blank>
