Hand held plane mirror and right angle mirror.

Hand held plane mirror and right angle mirror. When you are looking into a plane mirror, the image you see is 'perverted': your right ear becomes the left ear of the image. This perverted image is the same as if you made a thin translucent mask of your face and then pushed it inside-out. A right-angle mirror is made of two front-surface mirrors perpendicular to one another, with one edge touching. When you look into a right-angle mirror, you see a 'normal' image: your left ear is also the left ear of the image. Because light bounces twice to create this image, any irregularities in the symmetry of one's face are doubled in magnitude and made more noticeable.
