Question

hj and km are parallel lines. which angles are vertical angles? ∠mli and ∠kli ∠mli and ∠hig ∠mli and ∠kln ∠mli and ∠hil

Explanation:

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent. In the given figure, lines $GN$ and $KM$ intersect at point $L$. $\angle MLI$ and $\angle KLN$ are opposite each other at the intersection of these two lines.

Answer:

$\angle MLI$ and $\angle KLN$
