# Quick Answer: Is A Circle An Infinite Sided Polygon?

## Does a circle have 0 or infinite sides?

Infinite.

A circle has infinitely many infinitesimal sides.

Zero, if you wish to stick with the elementary geometry definition of “side”, which is a non-infinitesimal line segment with two end points each of which forms a vertex..

## Is a circle an Apeirogon?

Circle is the limit with the short possible side without changing what you have to begin with (think of increasing number of sides is just a consequence). Apeirogon is limit of the number of sides you add. They are different limits in that sense, roughly speaking.

## Is circle a regular shape?

Regular means predictable, with the fewest possible variations. So yes, a circle is about as regular as a shape can be. You can define a circle with just a center and a radius. Compare this, for example, to the shape of a human body, which would be rather irregular, requiring a lot of information to describe it fully.

## What is a 80 sided shape called?

octacontagonIn geometry, an octacontagon (or ogdoëcontagon or 80-gon from Ancient Greek ὁγδοήκοντα, eighty) is an eighty-sided polygon. The sum of any octacontagon’s interior angles is 14040 degrees.

## What is a 69 sided polygon called?

## What is an infinite sided shape called?

In geometry, an apeirogon (from the Greek word ἄπειρος apeiros, “infinite, boundless” and γωνία gonia, “angle”) or infinite polygon is a generalized polygon with a countably infinite number of sides.

## Can a polygon have an open side?

But first, we need to know what polygons are: polygons are several straight segments placed together. Polygons can be classified as open or closed. A polygon is open when the segments do not all connect at the beginning and end.

## What is a 70 sided shape called?

heptacontagonIn geometry, a heptacontagon (or hebdomecontagon from Ancient Greek ἑβδομήκοντα, seventy) or 70-gon is a seventy-sided polygon. The sum of any heptacontagon’s interior angles is 12240 degrees.

## Is a circle a polygon yes or no?

A figure or shape is not considered a polygon if it has rounded sides or if its sides intersects at any place other than at the ends of each side. Therefore a circle is not a polygon and an hourglass shape is not a polygon. Instead, it is two polygons, two triangles.

## What is a 1 million sided shape called?

megagonA megagon or 1 000 000-gon is a polygon with 1 million sides (mega-, from the Greek μέγας megas, meaning “great”). Even if drawn at the size of the Earth, a regular megagon would be very difficult to distinguish from a circle.

## What’s a 20 sided shape called?

icosagonIn geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.

## What is a 6 sided shape called?

hexagonMore than Four Sides A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides…

## Why is the circle not a polygon?

A polygon is a closed figure on a plane formed from a finite number of lines segments connected end-to-end. As a circle is curved, it cannot be formed from line segments, as thus does not fit the conditions needed to be a polygon.

## What is the most sided shape?

In geometry, the rhombicosidodecahedron, is an Archimedean solid, one of thirteen convex isogonal nonprismatic solids constructed of two or more types of regular polygon faces.It has 20 equilateral triangular faces, 30 square faces; a total of 50 faces, 12 regular pentagonal faces, 60 vertices, and 120 edges.More items…

## What is the weirdest shape in the world?

GömböcInvented by Hungarian mathematicians, the Gömböc can’t ever be kept down. It’s the world’s only artificial, self-righting shape.
