Thanks!
just spectacular-
The analytic involved is mind bending
thanks
Wish that better instruction on the constructions had been included in the text. To me that omission makes the book a bit more of a bookshelf book, and a bit less of a workshop book.
show me a method that produces a 9-sided polygon and I will be most impressed 😉
Go to the Wikipedia article for nonagon, and there’s an animation that illustrates an approximate construction that’s correct to within one part in 40,000.
That really is impressive – thanks for sharing!
Thanks to you at LAP and of course to Jim Tolpin for sharing this. A great work, bringing in a new consideration for me: the possibility to make all those constructions from scratch without using a square. some constructions i learne in a different way, nevertheless its very interesting and helpful. Will put some things into my daily work and order my copy at dictum in no time.
greetings, Alexander
