Brief Explanations

Vertical angles are pairs of opposite, non-adjacent angles formed by two intersecting lines. For $\angle KFL$, it is formed by lines $KH$ and $JL$ intersecting at point $F$. The angle opposite to it, sharing only the vertex $F$ and no common sides, is $\angle HFB$.

Answer:

$\angle HFB$
