due north = 0 degrees due east = 90 degrees due south = 180 degrees due west = 270 degrees Since a circle has 360 degrees, a compass has 360 degrees, too. North is at 0 degrees.
The cardinal points divide the circle into 4 equal parts. 360 divided by 4 = 90, so the cardinal points are 90 degrees apart. Therefore: North = 0 East = 90 South = 180 West = 270
The intercardinal points mark the midway point between the cardinal points. 90 divided by 2 = 45 Therefore: NE = 45 SE = 135 SW = 225 NW = 315
Note that the cardinal points are also 90 degrees apart, because there are four of them.
The secondary intercardinal points mark the midway points between the cardinal points and intercardinal points.
* The cardinal and intercardinal points are separated by 45 degrees. * 45 divided by 2 = 22.5
