A Round Or circle is the set of all points in a plane at a fixed distance, called the radius, from a fixed
point, the centre. The points can only be those that are part of a conic section; within the set of a plane
normal to the axis of a right cone. Circles are simple closed curves, dividing the plane into an interior and
exterior. Sometimes the word circle is used to mean the interior, with the circle itself called the
circumference(C). Usually, however, the circumference means the length of the circle, and the interior of
the circle is called a disk. An arc is any continuous portion of a circle...

Circles are named by their centre, e.g. Circle O. A circle curves to 360
degrees. The circle is the shape with the highest area for a given length
of perimeter.
• The circle is a highly symmetric shape, every line through the
center forms a line of reflection symmetry and it has rotational symmetry
around the centre for every angle. Its symmetry group is the orthogonal
group O(2,R). The group of rotations alone is the circle group T.
Numbers and the circle
The division of the circle into 360 degrees dates back to ancient India, as
found in the Rig Veda:
Twelve spokes, one wheel, navels three.
Who can comprehend this?
On it are placed together
three hundred and sixty like pegs.
They shake not in the least.
(Dirghatama, Rig Veda 1.164.48)
This division is used in mathematics, but also in geography and in
astronomy to measure the celestial sphere and equator (both in terms of
latitude and longitude).
The enneagram expresses the circle as equal to 9 integers. The structure
of the enneagram is based partly on the primary triangle of the circle at
0/360 degrees, 120 degrees and 240 degrees of the circle. In terms of
integers, these points of the circle correspond to the numbers 0/9, 3 and
6. The rest of the Enneagram structure consists of connections between
the other 6 integers of the 9-based number system - determined by the
fraction 1/7 = 0.142857 (repeating).
