Question

fh and ik are parallel lines. which angles are vertical angles? ∠fgj and ∠fge ∠fgj and ∠hgj ∠fgj and ∠ij g ∠fgj and ∠hge

Explanation:

Vertical angles are formed when two lines intersect. They are opposite each other and have equal measures. In the given figure, the intersection of lines $FH$ and $EL$ at point $G$ and lines $IK$ and $EL$ at point $J$ creates vertical - angle pairs. $\angle FGJ$ and $\angle HGE$ are opposite each other at the intersection of the lines and are vertical angles.

Answer:

$\angle FGJ$ and $\angle HGE$
