The four directions are commonly known as East, West, South, and North. These directions are based on the cardinal points of a compass and are used to navigate and determine the orientation of objects or places. East refers to the direction in which the sun rises, West is where the sun sets, South is opposite to the North Pole, and North is towards the North Pole. These directions are widely used in maps, navigation systems, and everyday life for giving directions and locating places.
