Question

In order to perform a reflection, which of the following must be drawn toaccurately map points onto their reflected images?a) Transversalsb) Perpendicular bisectorsc) Raysd) Transformation line

Answer 1

d) Transformation line

Explanation:

We need to draw the transformation line, to have an idea of where the coordinates will change.

Most are quite straightforward, like a reflection across the x-axis or the y-axis. But for example, if we want to reflect across x = 1, or y = 1, the transformation line helps finding the new coordinates.
