Question

which angles are adjacent to each other? ∠8 and ∠9 ∠7 and ∠8 ∠14 and ∠8 ∠14 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 ∠8 and ∠9: They do not share a common side.
• For ∠7 and ∠8: They share a common side and a common vertex and have no interior - points in common.
• For ∠14 and ∠8: They do not share a common side.
• For ∠14 and ∠1: They do not share a common side.

Answer:

∠7 and ∠8
