Very simple mirrors question

  1. Jan 6, 2017 #1
    The objective is to make a human able to see the front door while playing a piano using as few (plane) mirrors as possible (and where they would be positioned). And in what orientation will the human see the front door while looking in the mirror (flipped/mirrored or not). Also there's a third strange question, which is what would be the maximum amount of mirrors that can be used to complete the objective and why.


    I believe that it can be done with one mirror placed at the top (left to the orange couch). Whether the front door seen by the human is mirrored or not will depend on whether the amount of mirrors is odd or even from what I understand. I have completely no idea what to answer on the third strange question though.
