If the mirror is flat, it does not change the image scale. If the original light rays were parallel (like a laser), they stay parallel. If they weren't parallel, they continue to converge or diverge at the same rate as before the reflection.

Still puzzling about this. This page also says that about a flat mirror:

Image Size.

But it seems like you should be able to have a reflected image of the Sun on the Moon on the flat surface of a lake. But surely this image on the surface can't be the same *actual* size of the celestial body?
