In her cousin's new house, Xiaoli found that two flat mirrors were installed vertically on the dresser leaning against the corner, and the cosmetics in front of the mirrors were in the mirrors.

In the figure, 1 represents an object, 2 and 3 respectively represent images formed by two mirrors, 4 is formed by re-imaging the image of image 2 through mirror AB, and image 3 will also be imaged by mirror BC 5. When the object 1 is in front of the two mirrors, the image 45 just synthesizes an image, which is no longer opposite to the left and right of the object, but is consistent with the left and right of the object, that is, if you touch the left ear, the image will also touch the left ear.
