Question

which angles are vertical angles? ∠jkn and ∠lkn ∠jkn and ∠onp ∠jkn and ∠lki ∠jkn and ∠mnp

Explanation:

Step1: Recall vertical - angle definition

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

Step2: Analyze given angles

The lines $\overleftrightarrow{JL}$ and $\overleftrightarrow{MP}$ intersect at point $K$. $\angle{JKN}$ and $\angle{LKI}$ are opposite each other at the intersection of these two lines.

Answer:

$\angle{JKN}$ and $\angle{LKI}$
