Well, when you take a compass and draw a circle, and then you keep the same radius and mark off the circle with it, you get exactly six marks, dividing the line of the circle into six equal parts. So it seems like a circle just naturally wants to be partitioned into sixths. In order to divide the measurement of a circle equally into sixths, you have to have a total number of degrees that is a multiple of 6.
A hexagon made up of six equilateral triangles just fits inside the circle, with each triangle having all three sides equal to the radius of the circle. Any kid can prove this, drawing snowflakes inside circles with a dime-store compass.
The circle is divided into 360 segments and not a rounded off figure because of the ancient Babylonians. They used a system that our modern system is based off of where 60 was the base unit. This came from a tablet that was discovered that stated the ratio of the perimeter of a regular hexagon to the circumference of the circumscribed circle equals a number which is 1/6 of pi.
"Oct" is Latin for Eight. An Octagon would mean it can be divided into eight even parts
A closed figure made up of line segments is called a polygon. The segments in a polygon are called sides or edges.
A triangle is a geometric figure that is made of three line segments. It is a closed figure and has three angles.
a closed plane figure with 3 or more line segments is a polygon
A circle is not formed from line segments.
A pentagon
A polygon, if all the line segments are in the same plane.
Any closed figure formed by a set of straight linesegments is a polygon. If the segments are curved such as in a circle or oval, the closed figure is not a polygon.
If the line segments are straight, then it is a triangle.
A polygon.
