To determine if angles 1 and 2 are adjacent angles, we need to check for two main conditions:
- Common Vertex: Adjacent angles must share a common vertex.
- Common Side: Adjacent angles must share a common side.
If both of these conditions are met, then angles 1 and 2 are considered adjacent angles.
Since I cannot see the image you're referring to, I can't provide a definitive answer. However, based on the definitions:
- If the angles share a common vertex and a common side, the answer is Yes, the two indicated angles share a common vertex.
- If they only share a common side or neither condition is met, the answer would be No, the two indicated angles do not share a common side or No, the two indicated angles do not share a common vertex.
Please refer to the diagram and check these two conditions to determine if angles 1 and 2 are adjacent.
