Question

1. write all 4 correct ways to name ∠3.

Explanation:

Step1: Name by vertex

When naming an angle by its vertex, if there is only one angle at that vertex, we can use the vertex - point. Here, the vertex of ∠3 is G, so we can name it ∠G.

Step2: Name by three - point system

The three - point system for naming an angle requires the vertex point to be in the middle. So we can name ∠3 as ∠BGH, ∠HGB, and ∠EGH (since ∠EGH and ∠3 are the same angle).

Answer:

∠G, ∠BGH, ∠HGB, ∠EGH
