The questions are Why 360? and Why is 360 a full circle? Why not like the other numbers like 10 or 100?
-The Babylonians based their numbering system on base 60. This numbering system is called Sexagesimal System.
-The Babylonians beleived that the earth rotates 1 degree per day and realized that it takes 36o days (based on the Babylonian calendar) to make a one full earth year(one full rotation of the earth aroundn the sun). This way of thinking made sense to them that a full rotation is equal to 360 degrees .
(This shows the Earth's rotation around the sun)
-Another thing about 360 is that it is divisible to many numbers like 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, and 360.
