Question

bd and eg are parallel lines. which angles are adjacent angles? ∠dcf and ∠efc ∠dcf and ∠bcf ∠dcf and ∠efh ∠dcf and ∠gfh

Explanation:

Step1: Recall adjacent - angle definition

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

Step2: Analyze each option

• For $\angle DCF$ and $\angle EFC$, they do not share a common side.
• For $\angle DCF$ and $\angle BCF$, they share a common vertex $C$ and a common side $CF$. Also, they have no interior - points in common.
• For $\angle DCF$ and $\angle EFH$, they do not share a common side.
• For $\angle DCF$ and $\angle GFH$, they do not share a common side.

Answer:

$\angle DCF$ and $\angle BCF$
