Question

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

Explanation:

Step1: Recall adjacent - angle definition

Adjacent angles share a common vertex and a common side, and they do not overlap.

Step2: Analyze each option

• For $\angle DCA$ and $\angle EFC$, they do not share a common vertex or a common - side.
• For $\angle DCA$ and $\angle GFH$, they do not share a common vertex or a common - side.
• For $\angle DCA$ and $\angle DCF$, they share a common vertex $C$ and a common side $CD$.
• For $\angle DCA$ and $\angle EFH$, they do not share a common vertex or a common - side.

Answer:

$\angle DCA$ and $\angle DCF$
