# Quick Answer: Is A Polygon A 2d Shape?

## What is a 1 trillion sided shape called?

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

Apeirogons are the two-dimensional case of infinite polytopes..

## Are vertices on 2d shapes?

What properties do they have? 2D shapes have sides and vertices. A vertex is a point where two or more lines meet. The plural of vertex is vertices.

## What is a 13 sided shape called?

tridecagonIn geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon.

## What is a 16 sided shape called?

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

## Is rhombus a 2d shape?

2D shapes have only 2 dimensions and are flat e.g. square, rectangle, triangle, circle, pentagon, hexagon, heptagon, octagon, nonagon, decagon, parallelogram, rhombus, kite, quadrilateral, trapezium. 3D objects have three dimensions. The flat surfaces (faces) of many 3D objects are made up of 2D shapes e.g.

## What is a 15 sided shape called?

pentadecagonIn geometry, a pentadecagon or pentakaidecagon or 15-gon is a fifteen-sided polygon.

## What is a 20 sided polygon 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 2d polygon?

2-dimensional (2D) shapes have only two dimensions, length and width . A polygon is a closed 2D shape with straight sides. Polygons are named depending on the number of sides: Triangle (3 sides) Quadrilateral (4 sides)

## What is the shape of polygon?

This page examines the properties of two-dimensional or ‘plane’ polygons. A polygon is any shape made up of straight lines that can be drawn on a flat surface, like a piece of paper. Such shapes include squares, rectangles, triangles and pentagons but not circles or any other shape that includes a curve.

## What is a 100 sided shape called?

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 2 sided shape called?

digonIn geometry, a digon is a polygon with two sides (edges) and two vertices. Its construction is degenerate in a Euclidean plane because either the two sides would coincide or one or both would have to be curved; however, it can be easily visualised in elliptic space.

## What makes a 2d shape?

A 2D shape is a shape with two dimensions, such as width and height; a 3D shape is a shape with three dimensions, such as width, height and depth.

## What is a 14 sided shape called?

tetradecagonIn geometry, a tetradecagon or tetrakaidecagon or 14-gon is a fourteen-sided polygon.

## What 2d shape is not a polygon?

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 11 sided shape called?

hendecagonIn geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka “eleven” and –gon “corner”, is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim “eleven”.)

## What 2d shape has 4 equal sides?

rhombusA rhombus is a four-sided shape where all sides have equal length (marked “s”).

## What are shapes called?

Many two-dimensional geometric shapes can be defined by a set of points or vertices and lines connecting the points in a closed chain, as well as the resulting interior points. Such shapes are called polygons and include triangles, squares, and pentagons.

## What are 4 sided polygons?

A quadrilateral is a four-sided polygon with four angles. There are many kinds of quadrilaterals. The five most common types are the parallelogram, the rectangle, the square, the trapezoid, and the rhombus. Move your mouse cursor over the figures at the right to learn more.

## What is a 50 sided shape called?

pentacontagonIn geometry, a pentacontagon or pentecontagon or 50-gon is a fifty-sided polygon. The sum of any pentacontagon’s interior angles is 8640 degrees. A regular pentacontagon is represented by Schläfli symbol {50} and can be constructed as a quasiregular truncated icosipentagon, t{25}, which alternates two types of edges.

## What is a 9 sided shape called?

enneagonIn geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

## Is a polygon a 2d or 3d shape?

A polygon is a plane (2D) shape with straight sides.

## Is a polygon 2 dimensional?

A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon.

## What is a 1 billion sided shape called?

A 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.
