Why Is a Circle 360 Degrees? It was the Babylonians who first divided the circle into 360 degrees in order to integrate the geometry they developed with the 360-day calendar then in use. The Babylonians devised a counting system based not on units of 10 but on units of 60, which can be counted to on the 12 knuckles of one hand and the five ...

An 100-degree circle makes sense for base 10 people like ourselves. But the base-60 Babylonians came up with 360 degrees and we cling to their ways-4,400 years later. Then, there's also this discussion on Math Forum: In 1936, a tablet was excavated some 200 miles from Babylon.

Why is a Circle 360 Degrees? Date: 2 Jan 1995 15:16:33 -0500 From: Roy P. Sachs Subject: Origin of degrees Over the holiday, the question came up in a family discussion, and could easily come up in one of my geometry classes. What is the origin/basis of the degree measurement? Why is a circle divided into 360 degrees rather than some other number?

The When and Where of 360 Degrees. As you probably know, these days we humans like to divide a circle up into 360 pie-shaped wedges. Each of these wedges contains an angle at its vertex, and we say that the size of this angle is 1 degree.As you also probably know, degrees aren’t the only way we can measure angles.

This is a pet theory on why 360 degrees in a circle and should be treated as such, for ideas only. The Egyptian calendar had 12 months of 30 days each for 360 days. There were five additional days outside the months that the Greeks called epag...

Mesopotamians passed their base-60 numerical system to the ancient Egyptians, who used it to divide a circle into 360 degrees, and it worked out great. Degree is a unit to describe an angle. Degree divides the circle into 360 pieces, and the angle nearest to the center of the sector is 1 degree.
