Question

which angles are vertical angles? ∠jig and ∠hil ∠jig and ∠jil ∠mli and ∠jig ∠mli and ∠jil

Explanation:

Step1: Recall vertical - angles definition

Vertical angles are formed when two lines intersect. They are opposite each other and have equal measures.

Step2: Analyze the given angles

In the figure, the lines $\overleftrightarrow{KH}$ and $\overleftrightarrow{NG}$ intersect at point $I$. $\angle MLI$ and $\angle JIG$ are opposite each other at the intersection of the two lines.

Answer:

$\angle MLI$ and $\angle JIG$
