## What is a 16 sided shape called?

hexakaidecagonIn mathematics, a hexadecagon (sometimes called a hexakaidecagon or 16-gon) is a sixteen-sided polygon..

## 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.

## Are all Rhombi regular polygons?

A regular polygon must be both equiangular (all angle measures are the same) and equilateral (all side lengths are the same). A rhombus meets one of the requirements: it is equilateral. But, all of a rhombus’s angles are not the same. It is not equiangular, so it is not a regular polygon.

## What’s a 12 sided shape called?

dodecagonIn geometry, a dodecagon or 12-gon is any twelve-sided polygon.

## Are all closed shapes polygons?

A polygon is any closed, 2-dimensional figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.

## Is a closed plane figure always a polygon?

They can be closed or not closed. Plane figures made up of three or more closed line segments are polygons. Each line segment of a polygon is a side. Polygons are classified by the number of sides.

## Are open shapes never polygons?

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 17 sided shape?

heptadecagonIn geometry, a heptadecagon or 17-gon is a seventeen-sided polygon.

## Which figure is not a regular polygon?

A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons – a polygon, by definition, is made up of straight lines.

## What is a 100 sided shape?

hectogonIn geometry, a hectogon or hecatontagon or 100-gon is a hundred-sided polygon. The sum of all hectogon’s interior angles are 17640 degrees.

## What is a 99 sided shape called?

EnneacontagonIn geometry, an enneacontagon or enenecontagon or 90-gon (from Ancient Greek ἑννενήκοντα, ninety) is a ninety-sided polygon.

## What is an 18 sided shape?

OctadecagonOctadecagon. An 18-sided polygon, sometimes also called an octakaidecagon.

## What is a 10 sided shape called?

DecagonIn geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon.
