Talk:Angle trisection

From Wikipedia, the free encyclopedia

I, user:dino, wrote this from a re-direct. Yes, the diagrams are not so hot. But I wanted something "out there," perfect or not. Anyone with better software than the Dia (software) I used is welcome to replace them.

[edit] 2π/5

The article states that "For example, 2π / 5 radians (72°) may be constructed, and may be trisected. Also there are some angles, that are not-constructable, but (if somehow given) trisectable, e.g. 2π / 5." Surely 2π/5 cannot be both constructable and non-constructable? -Elmer Clark (talk) 10:05, 6 January 2008 (UTC)

Sure, correct example is 3π/7. It is not constructable, but (if somehow given) it is trisectable. —Preceding unsigned comment added by 213.171.48.226 (talk) 21:33, 23 January 2008 (UTC)
