ARC is a set of 10 equally spaced points from 0 to 90 degrees, on a circle of radius 2 centered at (5,5).
PENTAGON is a set of 6(!) equally spaced points from 0 to 360 degrees. This is the easiest way to get a pentagon, but you should really edit the file and remove the last point, since it repeats the first one. The alternative is to specify that the angles range from 0 to 288 degrees!
