The Compass Directions
Major Compass/Cardinal Directions
There are four major directions used to describe locations. These cardinal directions are:
North (N) South (S) East (E) West (W)
The four main directions, North, South, East and West, divide the angle at a point (360o), into four equal parts and each is 90o or a right angle.
Minor Cardinal Directions
Other minor cardinal directions are those that lie in the midpoints as follows:
North and East called North-East (NE)
South and East called South-East (SE)
South and West called South-West (SW)
North and West called North-West (NW)
These minor cardinal directions subdivide each right angle into two equal parts such that the angle between each major cardinal and minor direction is 45o.
