# Who invented 360 degrees? (2023)

## Who first used 360 degrees?

The Babylonians gave us the 360-degree circle. That number turns out to be the smallest one whose quotient is an integer when divided by any whole number from 1 through 10 (except for 7, which may have added to seven's stature as a "magic number".

When did we start using 360 degrees?

While we don't know exactly why the 360 degree convention was chosen (more on that in a minute), we do know approximately when and where it all started. At least we know that it came to be a long, long time ago—as in 4 or 5 thousand years ago with the Babylonians, the Greeks, and perhaps other even more ancient groups.

Who discovered degrees angles?

Aristarchus of Samos and Hipparchus seem to have been among the first Greek scientists to exploit Babylonian astronomical knowledge and techniques systematically. Timocharis, Aristarchus, Aristillus, Archimedes, and Hipparchus were the first Greeks known to divide the circle in 360 degrees of 60 arc minutes.

When was angle in degrees invented?

The history of the mathematical measurement of angles, possibly dates back to 1500BC in Egypt, where measurements were taken of the Sun's shadow against graduations marked on stone tables, examples of which can be seen in the Egyptian Museum in Berlin.

Did the Assyrians invent the 360 degree circle?

The Assyrians invented the world's first written language and the 360-degree circle, established Hammurabi's code of law, and are credited with many other military, artistic, and architectural achievements. For 300 years Assyrians controlled the entire Fertile Crescent, from the Persian Gulf to Egypt.

Why is 360 a special number?

360 is also a superior highly composite number, a colossally abundant number, a refactorable number and a 5-smooth number. 360 is the smallest number divisible by every natural number from 1 to 10 except 7. One of 360's divisors is 72, which is the number of primes below it.

How did we decide on 360 degrees?

The Mesopotamians passed their base-60 numerical system to the ancient Egyptians, who used it to divide a circle into 360 degrees, Mary Blocksma writes in her book Reading the Numbers. The 360-degree circle worked out great: The Egyptians loved perfect triangles, and exactly six of them fit into a circle.

Why is it 360 degrees and not 400?

The Babylonian numbering system of 4000 years ago was based on 60. Their calendar had 360 days and a complete cycle (or orbit of the sun by Earth) was divided into 360 units.

What is the 360-degree rule?

“There must be no more than the equivalent of four quarters of curves (a total of 360 degrees) between the points of traction, for example, pipe bodies and boxes.” Today we are entering the 360-degree bending rule for bending pipes.

Who created angles in math?

The first concept was used by Eudemus, who regarded an angle as a deviation from a straight line; the second by Carpus of Antioch, who regarded it as the interval or space between the intersecting lines; Euclid adopted the third concept.

## Who discovered triangle 180 degrees?

Over 2000 years ago the Greek mathematician Euclid came up with a list of five postulates on which he thought geometry should be built. One of them, the fifth, was equivalent to a statement we are all familiar with: that the angles in a triangle add up to 180 degrees.

Who created the 60 second minute?

Who decided on these time divisions? THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.

Who invented 90 degree angle?

Book 1 Postulate 4 states that all right angles are equal, which allows Euclid to use a right angle as a unit to measure other angles with. Euclid's commentator Proclus gave a proof of this postulate using the previous postulates, but it may be argued that this proof makes use of some hidden assumptions.

Who named angles?

Etymology. The name of the Angles may have been first recorded in Latinised form, as Anglii, in the Germania of Tacitus. It is thought to derive from the name of the area they originally inhabited, the Anglia Peninsula (Angeln in modern German, Angel in Danish).

What is the opposite of 180 or 360?

A circle has 360 degrees, so a 180 degree change (being half of 360 degrees) means you're now headed in the exact opposite direction. If you made a 360 degree change you would be heading in the exact same direction as when you started.

Why do people say 360 instead of 180?

A complete circle is 360 degrees. So, if you want to describe someone who has "come full circle," you might say he has made a 360-degree turn. A half circle, meanwhile, is 180 degrees. This is the phrase one might use to describe a complete change from one extreme to another.

## What is the most special number?

6174 is known as Kaprekar's constant after the Indian mathematician D. R. Kaprekar. This number is renowned for the following rule: Take any four-digit number, using at least two different digits (leading zeros are allowed).
