Question

which angles are vertical angles? ∠lki and ∠mnk ∠lki and ∠jkn ∠lki and ∠jki ∠lki and ∠lkn

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Analyze the given angles

In the figure, when two lines intersect at point \(K\), \(\angle LKI\) and \(\angle JKN\) are opposite each other at the intersection of the lines.

Answer:

\(\angle LKI\) and \(\angle JKN\)
