Answer

Brief Explanations:

Angles can be named by: 1) The vertex letter alone (when it's the only angle at that vertex), 2) Three letters with the vertex in the middle, using points from each side and the vertex, 3) A reversed version of the three-letter name (swapping the side points while keeping the vertex in the middle).

Answer:

$\angle H$ and $\angle IHG$ and $\angle GHI$
