  1. Thank you very much for the clear and pleasing presentation.

    If you collect a larger set of proofs without words, it would be very useful for all students (and teachers) of the non-English speaking countries like Iran.

  2. I examined and I found the proofs quite successful. Visual proofs are very useful…
