Question

name the marked angle in 2 different ways.

Explanation:

Step1: Identify the vertex and rays

The angle has vertex \( O \), with one ray \( OM \) and another \( ON \).

Step2: Name using three points

Using the three - point notation, the angle can be named \( \angle MON \) (or \( \angle NOM \)) as the middle letter is the vertex.

Step3: Name using the vertex

Since there is only one angle at vertex \( O \), it can also be named \( \angle O \).

Answer:

\( \angle MON \), \( \angle O \)
