Triangle PQR is reflected over a vertical line of reflection to create triangle P'Q'R' What are the coordinates of point R'?
If triangle PQR is reflected over a vertical line of reflection, then the x-coordinate of point R' will be the same as the x-coordinate of point R, but the y-coordinate will have the opposite sign.
Therefore, if the coordinates of point R are (x, y), then the coordinates of point R' will be (x, -y).
To find the coordinates of point R', we need to understand the effect of reflecting a point over a vertical line of reflection.
When a point is reflected over a vertical line, its x-coordinate remains the same, but its y-coordinate changes sign.
Assuming the coordinates of point R are (x, y), then the coordinates of point R' after reflection will be (-x, y).
Therefore, the coordinates of point R' are (-x, y).
To find the coordinates of R' after reflecting triangle PQR over a vertical line of reflection, you can use the concept of reflection, which involves flipping the shape over a line.
Let's assume that the vertical line of reflection is the y-axis, which means it has the equation x = 0. The reflection of a point across the y-axis is simply the point with the same x-coordinate but the opposite y-coordinate.
Given the coordinates of point R in triangle PQR, let's say it is (x, y):
1. Reflecting R over the y-axis will result in a point with the same x-coordinate but the opposite y-coordinate.
2. Since the y-axis is at x = 0, the x-coordinate of R' will be the same as the x-coordinate of R, which is x.
3. The y-coordinate of R' will be the opposite of the y-coordinate of R, so it will be -y.
Therefore, the coordinates of R' will be (x, -y).
