Question

Apply geometric motions to reflect figures. Brinda reflects point T over a line of reflection, resulting in point T′ . If points  T and  T′ have the same x-coordinate, what must be true?(1 point) Responses The line of reflection is horizontal. The line of reflection is horizontal. The line of reflection is the y-axis. The line of reflection is the y -axis. The line of reflection is the x-axis. The line of reflection is the x -axis. The line of reflection is vertical.

Answer 1

If points \( T \) and \( T' \) have the same x-coordinate after reflecting \( T \) over a line of reflection, then the line of reflection must be vertical.

This is because a vertical line of reflection does not change the x-coordinate of the points being reflected; it only changes the y-coordinate.

Thus, the correct response is:

**The line of reflection is vertical.**
