One degree (wey dem full call degree of arc, arc degree, or arcdegree), wey dem dey show with ° (the degree symbol), na measurement of plane angle, wey dem define so say one complete rotation na 360 degrees.

E no be SI unit, as the SI unit of angular measure na radian, but e dey mentioned for SI brochure as accepted unit. Because one complete rotation equal 2 radians, one degree equal radians.

The original reason why dem choose degree as unit of rotations and angles no dey clear. One theory talk say e get to do with the fact say 360 na almost the number of days for one year. Ancient astronomers notice say the sun, wey dey follow the ecliptic path throughout the year, dey move forward for the path by almost one degree every day. Some ancient calendars, like the Persian calendar, dey use 360 days for one year. The use of calendar wey get 360 days fit dey related to the use of sexagesimal numbers.

Another theory talk say the Babylonians divide circle using the angle of equilateral triangle as the basic unit and dem further divide am into 60 parts based on their sexagesimal numeric system. The earliest trigonometry, wey the Babylonian astronomers and their Greek successors use, dey based on chords of circle. A chord wey get length wey equal to the radius na natural base quantity. One sixtieth of this, based on their standard sexagesimal divisions, na one degree.``` <response>: ```1. 360 degrees
