Question

look at this angle: name this angle in three different ways:

Explanation:

Step1: Recall angle - naming rules

An angle can be named using the vertex letter alone (when there is only one angle at the vertex), or by using three points where the vertex is the middle - point.

Step2: Identify the vertex

The vertex of the angle is point $R$.

Step3: Name the angle

1. Using the vertex letter: $\angle R$.
2. Using three points with the vertex in the middle: $\angle SRT$.
3. Also using three points with the vertex in the middle: $\angle TRS$.

Answer:

$\angle R$, $\angle SRT$, $\angle TRS$
