The resulting image is no longer a rectangle because reflections do not preserve parallel and perpendicular lines.

The resulting image is no longer a rectangle because reflections preserve both parallel and perpendicular lines.

The resulting image is still a rectangle because reflections do not preserve parallel and perpendicular lines.
