(...) It would appear that they're approximately 126.8698976 degrees. That's from approximating some angles and noticing that what I think they were trying to do was to create the geometry such that a 3-4-5 right triangle was possible. DaveE (17 years ago, 10-Dec-07, to lugnet.technic, FTX)

Your best bet would be the #4 angle connector, its a 135 degree angle. (17 years ago, 10-Dec-07, to lugnet.technic)

I'm trying to make a largish (20 cm across or so) octagon or hexagon out of technic parts. I thought this would be easy, because I believed that the bent technic beams (e.g. (URL) 32348>) had a 135-degree angle, or at least some angle that would (...)
