What does it mean to reverse an image or create a mirror image?

Reversing an image or creating a mirror image involves flipping the image over a line, which effectively produces a reflection, similar to what you would see when looking in a mirror. This flipping action takes each point of the image and moves it to the opposite side of a designated line, maintaining the same distance from that line.

For example, if you have a letter or a shape, creating a mirror image would mean that the left side of the image becomes the right side and vice versa. This is distinctly different from the other transformations mentioned. Rotating would change the orientation of the image without necessarily reversing it, while translating involves shifting the image's position without altering its appearance. Projecting refers to creating a two-dimensional representation of a three-dimensional object, which does not pertain to creating a mirror image either. Therefore, flipping is the correct term that accurately describes the action of creating a mirror image.
