nA – (n-1)A – (n-2)A
(n-2)A – (n-1 – 2)A – (n-2-2)A

(f1-f4) – (f2-f6) – (f3-f7)

(if n(x)A=even– internal line; CW rotation); (else no internal line)

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?

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?

the rotations dont seem consistent

the difference between row 1 and row 2 only sort of seems like row 3 it isn't exact (for example the top of the triangle is not the same as the top of the pentagon)
