Question

name the highlighted arc.

Explanation:

An arc is named by its endpoints (or including an intermediate point to specify it is the minor arc, as this highlighted arc is shorter than the major arc between the two outer points). The highlighted arc spans from point W to point G, with point F lying on it, so we can name it using the endpoints and the intermediate point to clearly identify the correct arc.

Answer:

Arc WGF (or Arc FG W; the standard way is to list the endpoints with a middle point: $\text{Arc } WGF$)
