To determine if the indicated angles are adjacent, we need to know whether they share a common side and a common vertex. In this case, since rays A, B, and C all emerge from a common point O and create angles with each other, if the angles are formed by two rays sharing O as the vertex, they would be adjacent.
Without seeing the specific illustration, I can't definitively answer, but generally:
- Angles formed by different rays emerging from a common point that share a side and the same vertex are considered adjacent.
If that is the case in your illustration, the answer would be 1 (yes). If not, the answer would be 2 (no).
Please choose your answer based on this reasoning.
