Final answer:
The angle can be named as ∠GHK, ∠H, or ∠HGK, but not ∠angles.
Step-by-step explanation:
An angle is typically named by using three letters, where the vertex of the angle is the middle letter. The letters are chosen from the names of the three points that form the angle. In this case, the angle is formed by points G, H, and K. So, the correct expression to name the angle is ∠GHK.
The expressions ∠H and ∠HGK can also be used to name angles, as they follow the correct naming convention. However, ∠angles is not a valid expression to name the angle, as it does not represent any of the points that form the angle.
