I'm not exactly sure if this is a trig type thing. It just really seems like it. Suppose you attach a rope to the corner of a cube then suspend the cube. What will the angle be between the edges of the cube and the rope? If I hold a rubik's cube in my hand in a 2D perspective as just a square, the angle between the edges is 90 degrees, and the angle between either edge and where the rope would be should be the same. I would be able to say 2x + 90 = 360, x = 135 degrees. I can say that for all 3 ways of looking at that single corner of the cube (each corner has 3 adjacent planes). I can then draw 3 angles out from those 3 planes. What I want to know is how I can average those out or tie them together or something of that nature. Why was this moved to physics? It has essentially nothing to do with physics.
