Pent 4


















assuming the vertical
red pentagram line
(above) is supposed
to bisect the circle
start with that much
as known, or given...
instead of connecting dots...
i just center a line at a dot...
or known point, and rotate it
below, the second line in the pentagram (red line above)
is rotated 54 ...maintaining increments of 18 and 36 etc
