...any number that is evenly divisible by 9 will add up to 9 ... just so happens that 180 is divisible by 9, and from geometry the sum of the interior angles for all polygons add up to some multiple of 180 ... but what about measuring polygons in radians instead of degrees? Pi isnt divisible by 9... using 360 degrees or 2pi radians is an arbitrary system, I could invent a system that measures angle in units of twisters, for example, and say that a half-circle is 11 twisters, then someone would find out all about the prime number 11 and be like OMG, a square has 22 twisters, oh wow a pentagon has 33 twisters and a hexagon has 44 twisters ... game over dude, game over, haha ;)
