Question

Triangle ABC has been reflected over a vertical line of reflection.
The coordinates of vertices A, B, C, and B' are shown. What are the coordinates of vertex A'?
(1 point )

Answer 1

To find the coordinates of vertex A' after reflecting triangle ABC over a vertical line of reflection, you'll need to know the coordinates of vertex A and the equation of the line of reflection.

Assuming the vertical line of reflection is at x = k, the reflection of any point (x, y) over this line would be calculated using the formula:
\[
(x', y') = (2k - x, y)
\]
where \( (x', y') \) are the coordinates of the reflected point.

If you provide the coordinates of vertex A and the line of reflection (or the location of points B and B' which can help deduce it), I'd be able to calculate the coordinates of A' for you. Please provide the required details.
