Here's how it works:

* North is considered 0 degrees or 360 degrees.

* East is 90 degrees.

* South is 180 degrees.

* West is 270 degrees.

Any direction between these cardinal directions is measured using a degree value between the corresponding cardinal directions. For example:

* Northeast is between 0 and 90 degrees.

* Southeast is between 90 and 180 degrees.

* Southwest is between 180 and 270 degrees.

* Northwest is between 270 and 360 degrees.

You can use a compass to measure the specific degrees of a direction.
