Mirrors don't flip left and right, or up and down. They flip front and back.

- BenoitEssiambre 15y agoThis is the first part of the answer. The second part is that, since we define the left and right on an object relatively to its front and back, flipping the front and back also swaps how left and right are defined. There is no confusion with top and bottom as they are not defined relative to front and back.
- martincmartin 15y agoAbsolutely true.
- qntm 15y agoThis is the entire answer. It amazes me that people can write so much about this question without managing to get to this statement.
