Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

An angle can be named using the vertex point. Here the vertex is \(S\), so one way is \(\angle S\).

Step2: Use three - point naming

When naming an angle with three points, the vertex must be the middle point. For the marked angle with rays \(SR\) and \(ST\), it can be named \(\angle RST\) or \(\angle TSR\).

Answer:

\(\angle S\), \(\angle RST\)
