Answer:
Because the intercardinal directions present more specific information, allowing the direction of a region to be found more quickly.
Step-by-step explanation:
In short, the intercardinal directions optimize travel and the search for regions. This is because these directions are known as the intermediate directions, called northeast (NE), southeast (SE), southwest (SW) and northwest (NW). With the understanding of them it is possible to have more specific information about locations, allowing faster trips and more precise and specific directions.
