- To Gareth McCaughan.

- If I have misunderstood "your" folding procedure, I apologize.
- I regard point 3 of your construction as a "doubling".
- Then one of the angles of the regular pentagon is already
- established in point 2 of the construction.
- But this angle is 109.5 degrees and not 108 (the exact value).
- I get this both by calculations and by measuring the angle.
- Am I right?
-
- I enjoyed "your" folding procedure! It was new to me.
- I hope you also enjoy "mine".
