This is how it works: Each number you enter represents the number of degrees that stick will turn where the first box effects the first line etc.
So, if you were to enter 180 into all 5 boxes, all 5 sticks would move back and forth at 180 degrees, making a line, entering 90 into all 5 boxes makes a square, entering 1 makes a 360 sided figure. Also, if you add or subtract any multiple of 360 to a number, the result won't change.
You can also make sticks turn CCW with negative numbers, and turn sticks at different rates using... different numbers. I hope this helps!
Note: The number of degrees each stick turns is centered around it's joint to the stick before it
