Explanation:

Step1: Name the angle \( \angle SAC \)

An angle can be named by three points with the vertex in the middle. In \( \angle SAC \), \( A \) is the vertex. Another way to name it is \( \angle RAC \) since \( R,A,C \) are colinear in a way that represents the same angle as \( \angle SAC \) (as \( R - A - S \) are colinear on a straight - line).

Step2: Find a point on ray \( AS \)

A ray has an initial point and extends infinitely in one direction. Ray \( AS \) has initial point \( A \) and passes through \( T \) and \( S \). So a point on ray \( AS \) is \( T \) (or \( S \), but \( T \) is a valid answer from the given diagram's labeled points).

Step3: Determine the angle created by \( \overrightarrow{AR} \) and \( \overrightarrow{AB} \)

An angle is formed by two rays with a common vertex. The rays \( \overrightarrow{AR} \) and \( \overrightarrow{AB} \) have a common vertex \( A \). The angle formed is \( \angle RAB \) (using the three - point naming convention for angles with \( A \) as the vertex).

Answer:

1. \( \angle RAC \)
2. \( T \)
3. \( \angle RAB \)
