Question

which angles are adjacent to each other? ∠13 and ∠14 ∠5 and ∠2 ∠14 and ∠9 ∠2 and ∠15

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 ∠13 and ∠14: They share a common side and a common vertex, and have no interior - points in common.
• For ∠5 and ∠2: They do not share a common side or a common vertex.
• For ∠14 and ∠9: They do not share a common side or a common vertex.
• For ∠2 and ∠15: They do not share a common side or a common vertex.

Answer:

∠13 and ∠14
