Question

and are parallel lines.which angles are adjacent angles?andandandand

Explanation:

Step1: Recall the definition of adjacent angles

Adjacent angles share a common side and a common vertex, and have no overlapping interior points.

Step2: Analyze each option

• For \(\angle EFH\) and \(\angle GFC\): They do not share a common side.
• For \(\angle EFH\) and \(\angle DCF\): They do not share a common side or vertex.
• For \(\angle EFH\) and \(\angle GFH\): They share a common side \(FH\) and a common vertex \(F\), and have no overlapping interior points.
• For \(\angle EFH\) and \(\angle BCF\): They do not share a common side or vertex.

Answer:

\(\angle EFH\) and \(\angle GFH\)
