How the circle is divided

000 is Ākau, 090 Hikina, 180 Hema, 270 Komohana. Each quadrant is eight equal points of 11.25°. Ma leans a name toward the next; me keeps the name and carries the one before it. Northing is cos of the course, easting is sin, both on a unit circle.

The manuscript drawing this card is taken from is the restored scan.
