130 - 145

[Altruist]

yeah im mean these are kind of what i was referring to: semi-patterns

why does it stay (n-2)A between f3 and f4?

you're supposed to compare f1-f4-f7, f2-f5-f8 and f3-f6-f9

why does f6 have a line when it has an odd number of angles? (i guess im meant to assume the internal line isnt there first?

check "hint" in my post above

the rotations dont seem consistent

they are perfectly consistent. first next angle CW

the difference between row 1 and row 2 only sort of seems like row it isn't exact (for example the top of the trinage is not the same as the top of the pentagon)

it is exact. ignore inaccurate line-drawing, i couldnt bother. i m sure you can perceive the overlapping parts
