Question

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

Explanation:

Step1: Use vertex - based naming

An angle can be named by its vertex. Here the vertex is \(R\), so one way is \(\angle R\).

Step2: Use three - point naming

When naming an angle with three points, the vertex must be the middle point. So we can have \(\angle SRQ\) where \(S\) is a point on one ray and \(Q\) is a point on the other ray with \(R\) as the vertex.

Step3: Use another three - point naming

We can also write it as \(\angle QRS\) which is just the reverse order of the points in the three - point naming convention.

Answer:

\(\angle R\), \(\angle SRQ\), \(\angle QRS\)
