Question

which angles are vertical angles? ∠mln and ∠kli ∠mln and ∠mli ∠mln and ∠jig ∠mln and ∠hil

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are non - adjacent angles opposite each other.

Step2: Analyze each option

• For $\angle MLN$ and $\angle KLI$: They are adjacent angles formed by the intersection of lines, not vertical angles.
• For $\angle MLN$ and $\angle MLI$: They are adjacent angles, not vertical angles.
• For $\angle MLN$ and $\angle JIG$: $\angle MLN$ and $\angle JIG$ are vertical angles because they are non - adjacent angles formed by the intersection of two lines.
• For $\angle MLN$ and $\angle HIL$: They are not related as vertical angles.

Answer:

$\angle MLN$ and $\angle JIG$
