3D shapes have faces (sides), edges and vertices (corners)..

## 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.

## What is a 100000 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.

## 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.

## What is a 10 sided shape?

decagonIn geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°.

## What is a 20 sided shape?

## What is a 3d shape with 100 sides called?

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

## How many sides do 3d shapes have?

When we talk about the properties of these shapes we look at the number of sides that each shape has and the number of corners. A corner is where 2 sides meet. E.g. a triangle has 3 straight sides and 3 corners, whereas a circle has 1 curved side but no corners. 3D shapes A 3D shape is a blown up shape.

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.

Convex, cyclic, equilateral, isogonal, isotoxal. In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges.
