In geometry, a vertex is an angle (shape) associated with a vertex of an n-dimensional polytope. In two dimensions it refers to the angle formed by two intersecting lines, such as at a "corner" (vertex) of a polygon.

A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.

What is a 13 sided shape called?

A 13-sided polygon, sometimes also called the triskaidecagon.

What is a 14 sided shape?

A tetradecahedron is a 14-sided polyhedron, sometimes called a tetrakaidecahedron.

What is a 999 sided shape called?

This is still my favourite thing I discovered in maths. It's a polygon name builder. A 35-sided polygon is called a "triacontakaipentagon.“ A 672-sided polygon is a "hexahectaheptacontakaidigon.“ ... and 999 = enneahectaenneacontakaienneagon Kind of useless but fun.

What shape has the longest name?

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 regular triangular faces, 30 square faces, 12 regular pentagonal faces, 60 vertices, and 120 edges.

What's a 20 sided shape called?

In geometry, a 20 sided shape, i.e. 2d shape is called an icosagon. The sum of all the interior angles of an icosagon is 3240 degrees. An icosagon with all equal sides is called a regular icosagon.

What is a 20 sided shape called 3D?

An Icosahedron is a 3D shape that has 20 faces. The name comes from the Greek word eikosi, meaning 'twenty', and hedra, meaning 'seat'.

Is there a shape with 100 sides?

A 100-sided polygon is called a hectogon.

What shape is a hendecagon?

In 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 is a undecagon shape?

In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. The sum of all the interior angles of a hendecagon is 1620 degrees.

Is there an infinite sided shape?

In 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.

Is the Megagon a circle?

A Megagon is a polygon with 1,000,000 sides and angles. Even if drawn at the size of the earth, it would still be very hard to visually distinguish from a circle.

What is a 1000000 sided shape called?

A megagon or 1,000,000-gon is a polygon with one million sides (mega-, from the Greek μέγας, meaning "great", being a unit prefix denoting a factor of one million).

What is a 777 sided shape?

means 7, heptaconta means 70, and heptahecta means 700. Thus, the polygon has 777 sides. the word “gon” with the number of sides (n-gons) for polygons beyond enneagons and decagons.
