#1-2 name each angle in three different ways

1. __, , __

diagram with points e, i (on a horizontal ray), n (on a downward ray) forming an angle at e

Explanation:

Step1: Recall angle naming rules

An angle can be named by its vertex, by three points (with the vertex in the middle), or by a number (if labeled). Here, the vertex is \( E \), and the sides are \( \overrightarrow{EI} \) and \( \overrightarrow{EN} \).

Step2: Name using vertex

Using the vertex, the angle is \( \angle E \).

Step3: Name using three points

Using three points (with \( E \) as the vertex), the angle can be \( \angle IEN \) or \( \angle NEI \).

Answer:

\( \angle E \), \( \angle IEN \), \( \angle NEI \)
