Why are there 360 degrees in a circle?

Answer 1

Imagine a triangle ABC inside a circle.

BC Arc = 2 x

BC Arc + AC Arc + AB Arc = 2

= 2(

= 2 x 180

= 360 degree

The answer to why there are 360 degrees in a circle is as simple as why Christmas Day, 25th December is the 360th day of the year. The architects of our modern calendar ensured that we would never forget when the sun begins its journey back to the Equator after the Winter Solstice. To the naked eye, it appears as though the sun never sets at a lower point on the horizon than it does on the first day of a solstice, and then sets at that same point of entry for 3 sunsets (the same period that a full moon appears to last). This happens twice a year, thus the Tropic of Cancer and the Tropic of Capricorn. The total of 6 sunsets during the solstices of 6+ 24 hour periods or 7 days during this period is the basis of why there are 7 days in a week. In short, to the naked eye, there are 360 different sunset points of entry on the horizon during a calendar year i.e. 90 points / days between Winter Solstice to Equinox, Equinox to Summer Solstice, Summer Solstice to Equinox and then Equinox to Winter Solstice. Sounds like the beginnings of Geometry to me. There are always simple and practical explanations for these questions, even if it did take me years to figure it out. One simply needs to observe the nature of nature. david lee
