Question

which angles are adjacent to each other? ∠6 and ∠7 ∠7 and ∠5 ∠8 and ∠1 ∠5 and ∠1

Explanation:

Step1: Recall adjacent - angle definition

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

Step2: Analyze each option

• For $\angle6$ and $\angle7$: They share a common side and a common vertex, and no interior - points in common.
• For $\angle7$ and $\angle5$: They do not share a common side.
• For $\angle8$ and $\angle1$: They do not share a common side or a common vertex.
• For $\angle5$ and $\angle1$: They do not share a common side or a common vertex.

Answer:

$\angle6$ and $\angle7$
