Answer:
∠G
Step-by-step explanation:
First, we have to recognize that D, H, and G all lie on one line. Furthermore, E, F, and G lie on another line. From that, we can see that ∠G can be written as ∠DGE, ∠HGE, ∠DGF, or ∠HGF. In other words, ∠G = ∠DGE = ∠HGE = ∠DGF =∠HGF. Since each triangle has at least one of these names of this angle, (∠DGF and ∠EGH), ∠G is common to both.
*assuming ∠G is the top angle that is cut off in the picture.
