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

Explanation:

Step1: Recall angle - naming rules

An angle can be named using the vertex and points on its rays.

Step2: Name with vertex in the middle

One way to name the angle is $\angle PRQ$. Here, the vertex $R$ is in the middle and $P$ and $Q$ are points on the rays.

Step3: Name with vertex only

Since there is only one angle at vertex $R$, it can be named $\angle R$.

Step4: Name in reverse order

Another way is $\angle QRP$.

Answer:

$\angle PRQ$, $\angle R$, $\angle QRP$
