Question

which angles are vertical angles? ∠kjh and ∠ijh ∠lmo and ∠nmo ∠nmo and ∠kjh ∠ijh and ∠nmj

Explanation:

Step1: Recall vertical - angle definition

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

Step2: Analyze each option

• For $\angle KJH$ and $\angle IJM$, they are vertical angles because they are formed by the intersection of lines $IK$ and $HO$ and are non - adjacent and opposite each other.
• $\angle LMO$ and $\angle NMO$ are adjacent angles, not vertical angles.
• $\angle NMO$ and $\angle KJH$ are not related as vertical angles.
• $\angle IJM$ and $\angle NMJ$ are adjacent angles, not vertical angles.

Answer:

$\angle KJH$ and $\angle IJM$
