222.508 would be phi^2 and 275 might be 2 phi Radius = 1
do this test: get three equal length sphere magnets (I used Neodymium Iron Boron) and mark the center theta for the first magnets . set up the 2 magnets on either poles of the third magnet without touching every different (the first magnets) you get the angle from the center of the two magnets that intersects about 85 stages by 137.five by 137.5 . The association of the three magnets need to appear like Y

Ah , thank you for making my explanations more clear. :)

hello is there a way to draw a 137.5 by 85 degree angle using only a compass and a straight edge?

Hi Bob - I'm sorry I don't understand your question, is that something you're trying to draw in MoI ?

Yes, I'm trying to construct a Golden angle of 137.5 by 137.5 by 85 degrees approximate in a circle using a compass and a straight edge.Which can be done on a piece of paper.

I recall from math class that the square root of 5 can be so constructed...

According to this link, the answer is YES :-)

But the method is not given...
- Brian
After reading google links on "Constructible Angles," I'll conclude that construction of 137.5 degrees is NOT possible with compass and straigtedge...
