# How to Calculate Hexagon Chart Angles

**Ever wonder how to calculate an angle on WD Gann's hexagon chart? Here is the formula**

1 equates to 360 degrees. Therefore .5 equates to 180 degrees and .25 to 90. (But just like the sq9 calcs., not exactly) let "a" be your number or price or whatever then a = 3n(n-1) your first step of course is to solve for n which is not as easy as taking the square root but almost. Remember the quadratic equation? n = (3 + (9 + 12*a)^{½})/6 lets say your number is 36 and you want to add 90 degrees 1. first find n n = (3 + (9 + 12*36)^{½})/6 = 4 (In case its not clear… we are taking the square root of the term (9 + 12*36) in the above equation) 2. since 1 => 360 degrees , .25 => 90 degrees adding that to the n = 4 gives 4.25 therefore your target becomes: a' = 3*4.25(4.25 -1) = 41.4 <- not quite 42 like it should be but close enough don't you agree? Remember… the Square of 9 (Futia) formula is: degrees = (180*P^{½}-225)*360 (degrees)
