Question

which angles are adjacent angles?
∠ihf and ∠lkm
∠ihf and ∠ghk
∠ihf and ∠lkh
∠ihf and ∠ghf

Explanation:

Step1: Recall the definition of adjacent angles

Adjacent angles have a common vertex and a common side.

Step2: Analyze each pair

• For \(\angle IHF\) and \(\angle LKM\): No common vertex.
• For \(\angle IHF\) and \(\angle GHK\): No common vertex.
• For \(\angle IHF\) and \(\angle LKH\): No common vertex.
• For \(\angle IHF\) and \(\angle GHF\): They have a common vertex \(H\) and a common side \(HF\).

Answer:

\(\angle IHF\) and \(\angle GHF\)
