Objective: Explore impossible objects and Escher's prints based on impossible figures.

  1. Decide which of the following 9 figures are impossible, and which ones are possible. For some you should look at the cross-sections like we discussed last time. For others you may want to draw the vanishing lines. Some may be ambiguous. Carefully explain which figures you think are possible and which ones you think are impossible. Impossible.png
  2. What's wrong with the following figure?
  3. Escher constructed several prints based on impossible figures. For the following indicate what technique(s) he used to construct these impossible worlds. a. Relativity b. Belvedere c. Still Life with Mirror d. Still Life with Street
