  6. Attract the keeping sectors. Initial, lengthen a line from the correct that mirrors the inbound leg. This is the border among the parallel and the teardrop sectors. 2nd, draw a further line as a result of the resolve that produces a 70 degree angle with the other line on the major of the holding aspect. You really should now have a few sectors:
    • a. 70 levels is the teardrop sector
    • 110 degrees for the parallel sector
    • 180 degrees for the direct sector.
