To determine the coordinates of the reflected vertex A′, we need to know the coordinates of vertex A and the position of the vertical line of reflection.
Generally, when a point (x, y) is reflected over a vertical line (like x = k), the new point A′ will have the same y-coordinate but the x-coordinate will mirror over the line of reflection. The formula for reflecting a point (x, y) over a vertical line x = k is as follows:
- A(x, y) becomes A′(2k - x, y)
If you provide the coordinates of vertex A and the vertical line of reflection, I can calculate the coordinates of A′ for you!
