Question

select a pair of opposite rays. r s t rs st rt ts

Explanation:

Step1: Recall definition of opposite rays

Opposite rays are two rays that have the same endpoint and extend in opposite directions to form a straight - line.

Step2: Analyze given rays

In the given set of points \(R\), \(S\), and \(T\) on a line, ray \(\overrightarrow{ST}\) and ray \(\overrightarrow{TS}\) have the same endpoint \(S\) (for \(\overrightarrow{ST}\)) and \(T\) (for \(\overrightarrow{TS}\)) and extend in opposite directions.

Answer:

\(\overrightarrow{ST}\) and \(\overrightarrow{TS}\) (assuming Option 2 is \(\overrightarrow{ST}\) and Option 4 is \(\overrightarrow{TS}\))
