Question

which angles are adjacent to each other? ∠12 and ∠15 ∠13 and ∠15 ∠13 and ∠14 ∠16 and ∠11

Explanation:

Step1: Recall the definition of adjacent angles

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

Step2: Analyze each option

• For \(\angle12\) and \(\angle15\): They do not share a common side or vertex.
• For \(\angle13\) and \(\angle15\): They do not share a common side or vertex.
• For \(\angle13\) and \(\angle14\): They share a common side and a common vertex, and have no overlapping interior points.
• For \(\angle16\) and \(\angle11\): They do not share a common side or vertex.

Answer:

\(\angle13\) and \(\angle14\)
