Question

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

Explanation:

Step1: Use vertex - centered naming

An angle can be named by its vertex when there is only one angle at that vertex. Here the vertex is \(H\), so one name is \(\angle H\).

Step2: Use three - point naming

We can name the angle using three points where the middle point is the vertex. So we can have \(\angle GHI\) and \(\angle IHG\).

Answer:

\(\angle H\), \(\angle GHI\), \(\angle IHG\)
