Question

which angles are adjacent angles?

∠hif and ∠gfi
∠hif and ∠efd
∠hif and ∠gfd
∠hif and ∠jif

Explanation:

Step1: Recall the definition of adjacent angles

Adjacent angles share a common vertex and a common side.

Step2: Analyze each option

• For \(\angle HIF\) and \(\angle GFI\): No common vertex.
• For \(\angle HIF\) and \(\angle EFD\): No common vertex.
• For \(\angle HIF\) and \(\angle GFD\): No common vertex.
• For \(\angle HIF\) and \(\angle JIF\): Share vertex \(I\) and side \(IJ\).

Answer:

\(\angle HIF\) and \(\angle JIF\)
