Question

bd and eg are parallel lines. which angles are adjacent angles? ∠gfh and ∠dcf ∠gfh and ∠gfc ∠gfh and ∠efc ∠gfh and ∠bca

Explanation:

Step1: Recall adjacent - angle definition

Adjacent angles share a common vertex and a common side.

Step2: Analyze each option

• For $\angle GFH$ and $\angle DCF$, they do not share a common vertex or side.
• For $\angle GFH$ and $\angle GFC$, they share the common vertex $F$ and the common - side $\overrightarrow{FH}$.
• For $\angle GFH$ and $\angle EFC$, they do not share a common side.
• For $\angle GFH$ and $\angle BCA$, they do not share a common vertex or side.

Answer:

$\angle GFH$ and $\angle GFC$
