Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

We can name an angle by its vertex. If the vertex is the only angle at that point, we can call it ∠I.

Step2: Use three - point naming

We can also name the angle using three points on the rays and the vertex. The angle can be named as ∠HIJ (where I is the vertex and H and J are points on the two rays forming the angle).

Answer:

∠I, ∠HIJ
