The ancient Greeks used base 6 numbers and thought that the number 6 had some kind of power. This thinking was backed up by the number of days in a year. When the Ancients went about measuring the year, they watched the sun set each day over the horizon. Where it set, it would be marked on a circle. After a while, they noticed that about 360 of these evenly spaced marks would fill up a circle. Any rounding error is because of the power of the number 6 and 6*6=36 and so this was special too and the number of degrees of a circle became 360. 360/24=15degrees => the earth turns 15 degrees in an hour 60 seconds a minute, 60 minutes an hour => 3600 seconds and hour This is also why angles are measure by degrees (o), minutes ('), and seconds ("). 360 degrees is an arbitrary number that (roughly) matches the length of the year by chance. Gradients are another measurement of angle defined as there being 100 (an arbitrary number based on our number system) Gradients in a circle. A better mathematical measurement of angles is radians. There are pi~3.141 radians in a circle.

What is sum of interior and exterior angles of a concave quadrilateral?
-- The sum of exterior angles of any polygon is 360 degrees.-- The sum of interior angles of any quadrilateral, no matter what shape, is 360 degrees.-- 360 + 360 = 720 degrees.
In what order does the degrees go when measuring angles?
The order of degrees when measuring angles is as follows: 0 degrees, 90 degrees, 180 degrees, 270 degrees, and 360 degrees.
Does a rectangle equal 360 degrees?
No, a rectangle does not equal 360 degrees. The sum of the interior angles of a rectangle is 360 degrees, but a rectangle itself is a shape defined by its four right angles, each measuring 90 degrees. Therefore, while its angles sum to 360 degrees, the rectangle as a shape is not equal to that measurement.

Circles and angles Find d 140 100 80 degrees?
To find the missing angle ( d ) in a circle with angles measuring 140 degrees, 100 degrees, and 80 degrees, we can use the fact that the sum of angles around a point is 360 degrees. Therefore, we can set up the equation: ( d + 140 + 100 + 80 = 360 ). Simplifying this gives ( d + 320 = 360 ), so ( d = 360 - 320 = 40 ) degrees.
How to use Protractor effectively for measuring angles accurately?
To use a protractor effectively for measuring angles accurately, place the center of the protractor on the vertex of the angle. Align one side of the angle with the 0-degree mark on the protractor. Read the measurement where the other side of the angle intersects the protractor. Make sure to use the correct scale (either 180 degrees or 360 degrees) based on the type of angle you are measuring.
What is a polygon with all the interior angles measuring 900?
The angle must be somewhere between zero and 360 degrees.
If two angles in a parallelogram are equal to 35 degrees what are the measurements of the other two angles?
The sum of the internal angles in a parallelogram is 360 degrees. Since there are two equal pairs of angles measuring the same, then each of the second pair of angles is equal to (360 - (35 x 2)) / 2 = 145 degrees.

How many angles make a full turn?
A full turn is equal to 360 degrees, which can be divided into various angles. For example, it can be made up of 360 one-degree angles, 180 two-degree angles, or 90 four-degree angles. In terms of right angles, a full turn consists of 4 right angles (each measuring 90 degrees).
