To find the vertices of triangle \( A'B'C' \) after reflecting triangle \( ABC \) across the x-axis and the y-axis, we follow these steps:
1. **Reflect across the x-axis**: This changes the sign of the y-coordinate of each vertex.
2. **Reflect across the y-axis**: This changes the sign of the x-coordinate of each vertex.
Assuming the original coordinates of the triangle vertices are:
- \( A(x_A, y_A) \)
- \( B(x_B, y_B) \)
- \( C(x_C, y_C) \)
Reflecting each point:
- \( A' = (-x_A, -y_A) \)
- \( B' = (-x_B, -y_B) \)
- \( C' = (-x_C, -y_C) \)
Now, we need to analyze the given options for triangle \( A'B'C' \):
1. **Reflecting the points (outcomes):**
- If \( A(-2,1) \), then reflecting gives \( A' = (2,-1) \).
- If \( B(-6,3) \), then reflecting gives \( B' = (6,-3) \).
- If \( C(-1,3) \), then reflecting gives \( C' = (1,-3) \).
Now let's analyze the responses:
1. \( A'(-2, 1), B'(-6, 3), C'(-1, 3) \)
2. \( A'(2, 1), B'(6, 3), C'(1, 3) \)
3. \( A'(-2, 1), B'(-1, 3), C'(-6, 3) \)
4. \( A'(-2, -1), B'(-6, -3), C'(-1, -3) \)
The correct reflection results are not given on the list provided. The correct transformation steps lead to:
- If the original coordinates are not listed, we specifically cannot choose. However, double-checking the transformations can lead to misreporting.
Please confirm your initial triangle coordinates for a clear choice or clarification on which transformation approach/articulation was noted for the original triangle vertices.

Thank you for providing the coordinates of the vertices of triangle \( ABC \):
- \( A(2, -1) \)
- \( B(6, -3) \)
- \( C(1, -3) \)
Now, let's reflect triangle \( ABC \) across the x-axis and the y-axis:
1. **Reflect across the x-axis**:
- \( A(2, -1) \) becomes \( A'(2, 1) \)
- \( B(6, -3) \) becomes \( B'(6, 3) \)
- \( C(1, -3) \) becomes \( C'(1, 3) \)
2. **Now, reflect across the y-axis**:
- \( A'(2, 1) \) becomes \( A''(-2, 1) \)
- \( B'(6, 3) \) becomes \( B''(-6, 3) \)
- \( C'(1, 3) \) becomes \( C''(-1, 3) \)
The final vertices of triangle \( A'B'C' \) after reflecting across both axes are:
- \( A''(-2, 1) \)
- \( B''(-6, 3) \)
- \( C''(-1, 3) \)
Thus, the answer is:
The vertices of triangle \( A'B'C' \) are \( A'(-2, 1), B'(-6, 3), C'(-1, 3) \).
This matches the response:
- The vertices of triangle \( A'B'C' \) are \( A'(-2, 1) \), \( B'(-6, 3) \), \( C'(-1, 3) \).
- \( A(2, -1) \)
- \( B(6, -3) \)
- \( C(1, -3) \)
Now, let's reflect triangle \( ABC \) across the x-axis and the y-axis:
1. **Reflect across the x-axis**:
- \( A(2, -1) \) becomes \( A'(2, 1) \)
- \( B(6, -3) \) becomes \( B'(6, 3) \)
- \( C(1, -3) \) becomes \( C'(1, 3) \)
2. **Now, reflect across the y-axis**:
- \( A'(2, 1) \) becomes \( A''(-2, 1) \)
- \( B'(6, 3) \) becomes \( B''(-6, 3) \)
- \( C'(1, 3) \) becomes \( C''(-1, 3) \)
The final vertices of triangle \( A'B'C' \) after reflecting across both axes are:
- \( A''(-2, 1) \)
- \( B''(-6, 3) \)
- \( C''(-1, 3) \)
Thus, the answer is:
The vertices of triangle \( A'B'C' \) are \( A'(-2, 1), B'(-6, 3), C'(-1, 3) \).
This matches the response:
- The vertices of triangle \( A'B'C' \) are \( A'(-2, 1) \), \( B'(-6, 3) \), \( C'(-1, 3) \).
