In the context of naming angles, the following notations can be valid for a right angle labeled with points A, B, and C, where point B is the vertex of the angle:
1. **∠BCA** - Correct, because it describes the angle formed at B with points C and A.
2. **∠B** - Correct, as it directly names the angle at vertex B.
3. **∠C** - Incorrect; this refers to a point, not an angle.
4. **∠ABC** - Correct, as it describes the angle formed at B with points A and C.
Thus, the valid names for the angle are: **∠BCA, ∠B, and ∠ABC**.
1. **∠BCA** - Correct, because it describes the angle formed at B with points C and A.
2. **∠B** - Correct, as it directly names the angle at vertex B.
3. **∠C** - Incorrect; this refers to a point, not an angle.
4. **∠ABC** - Correct, as it describes the angle formed at B with points A and C.
Thus, the valid names for the angle are: **∠BCA, ∠B, and ∠ABC**.
