The mirrors do not turn left to right. They blur front and back. The mirrors show the rays of light that the display angle is equal to the angle of the event. In the three-dimensional object standing in front of the mirror, there is a picture of the object created behind the mirror on the right-hand side, left-handed left side, top left side, bottom side, but the front side is turned back and the back side is investigated. This can be easily seen by following the rays from the key points in the object and seeing where it ends in the mirror. The diagram to the right shows the result, which ensures that the mirrors only glow in the front and back.
