Question

which angles are adjacent to each other? ∠ced and ∠ibj ∠ghb and ∠kal ∠bec and ∠kal ∠dea and ∠aeb

Explanation:

Step1: Recall adjacent - angle definition

Adjacent angles share a common vertex and a common side.

Step2: Analyze each option

• For $\angle CED$ and $\angle IBJ$, they do not share a common vertex or side.
• For $\angle GHB$ and $\angle KAL$, they do not share a common vertex or side.
• For $\angle BEC$ and $\angle KAL$, they do not share a common vertex or side.
• For $\angle DEA$ and $\angle AEB$, they share a common vertex $E$ and a common side $\overrightarrow{EA}$.

Answer:

$\angle DEA$ and $\angle AEB$
