Answer:

•Defination:-

A compass is a magnetometer used for navigation and orientation that shows direction relative to the geographic cardinal directions. Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials.

•Origin:-

The compass was invented in China during the Han Dynasty between the 2nd century BC and 1st century AD where it was called the "south-governor" (sīnán 司南). The magnetic compass was not, at first, used for navigation, but for geomancy and fortune-telling by the Chinese.

•Degrees:-

Direction as Degrees

Since the Second World War compasses have been graduated in the 360 degrees (°) of a circle. Thus 000° or 360° is north, 090° is east, 180° is south, and 270° is west. A direction of 154° is between east and south and 321° is roughly northwest.
