To reflect a triangle across the x-axis and the y-axis, we need to modify the coordinates of each vertex.
1. **Reflect across the x-axis:** Change the sign of the y-coordinate.
2. **Reflect across the y-axis:** Change the sign of the x-coordinate.
Given the original vertices of triangle ABC:
- A(2, 1)
- B(1, 3)
- C(6, 3)
**Step 1: Reflect across the x-axis:**
- A(2, 1) becomes A(2, -1)
- B(1, 3) becomes B(1, -3)
- C(6, 3) becomes C(6, -3)
**Step 2: Reflect across the y-axis:**
- A(2, -1) becomes A'(-2, -1)
- B(1, -3) becomes B'(-1, -3)
- C(6, -3) becomes C'(-6, -3)
Therefore, the vertices of triangle A′B′C′ are:
- A′(-2, -1), B′(-1, -3), and C′(-6, -3).
The correct choice is:
**The vertices of triangle A′B′C′ are A′(−2,−1), B′(−1,−3), and C′(−6,−3).**
1. **Reflect across the x-axis:** Change the sign of the y-coordinate.
2. **Reflect across the y-axis:** Change the sign of the x-coordinate.
