          (! 6.5 \rAngleB\space cos mul 6.5 \rAngleB\space sin mul)%
          (! /a \rAngleB\space 7.75 sub def 8 a cos mul 8 a sin mul)%
          (! /a \rAngleB\space 10.25 sub def 7 a cos mul 7 a sin mul)%
          (! /a \rAngleB\space 11.25 sub def 8 a cos mul 8 a sin mul)
          (! /a \rAngleA\space 11.25 add def 8 a cos mul 8 a sin mul)
          (! /a \rAngleA\space 10.25 add def 7 a cos mul 7 a sin mul)%
          (! /a \rAngleA\space 7.75 add def 8 a cos mul 8 a sin mul)%
          (! 6.5 \rAngleA\space cos mul 6.5 \rAngleA\space sin mul)%

you need a closed path to fill something. "(! " starts a postscript
command sequence. It is nearly the same like the code from
the HP pocket calculators. The first solution with the polar coordinates
is a bit tricky. It does not has a closed path, so you are not able to
start a fill command.
