To reflect a triangle across the y-axis, we take each point and change the sign of its x-coordinate while keeping the y-coordinate the same.
Assuming the original coordinates of triangle \( \triangle A'B'C' \) are:
- \( A' (x_1, y_1) \)
- \( B' (x_2, y_2) \)
- \( C' (x_3, y_3) \)
The reflected coordinates across the y-axis for the new triangle \( \triangle A"B"C" \) will be:
- \( A" (-x_1, y_1) \)
- \( B" (-x_2, y_2) \)
- \( C" (-x_3, y_3) \)
To provide the specific new coordinates, please share the original coordinates for \( A' \), \( B' \), and \( C' \).
