Q.
  Three plane mirrors are mounted on three walls forming an isosceles right triangle as shown in the figure. How many images are formed in all?  Draw a diagram and incident the position of the images.

Dear student,
Infinite number of images are formed between the three plane mirrors of same size.Because it is a closed structure and continuos reflection of light rays will result in formation of images(images of images ). 

Theoretically there shall be infinite images as every virtual image there shall one ore more virtual images formed by other mirror/s.Practically the remote images may not be visible.This is demonstrated in kaleidoscope.
