**What is a 11 sided shape called?**

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 14 Gon?**

**What are the 20 polygons?**

In geometry, a chiliagon (/ˈk?li?g?n/) or 1000-gon is a **polygon** with 1,000 **sides**. Philosophers commonly refer to chiliagons to illustrate ideas about the nature and workings of thought, meaning, and mental representation.

**Can polygons have curves?**

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.

**Is there a shape with 2 sides?**

In 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 is a 19 sided polygon?**

In geometry an enneadecagon or **19**-gon is a **nineteen**–**sided polygon**. It is also known as an enneakaidecagon or a nonadecagon.

**What is the largest polygon?**

Myriagon. In geometry, a myriagon or 10000-gon is a **polygon** with 10,000 sides. Several philosophers have used the regular myriagon to illustrate issues regarding thought.

**What is a 14 Gon?**

**Is a trapezoid a polygon?**

A **trapezoid** is a four-sided shape with at least one set of parallel sides. Finally, a **polygon** is a closed, two-dimensional shape with many sides. Everything from a triangle to an octagon to a megagon is a type of **polygon**.

**Can a polygon have curved sides?**

No. A **polygon** by definition **has** straight line segments as its **sides**. If a geometrical figure **has curved sides**, it is not considered a **polygon**. A regular **polygon has** an interior angle that is twice the exterior angle.

**What is a 20 Gon?**

Convex, cyclic, equilateral, isogonal, isotoxal. In geometry, an icosagon or **20**–**gon** is a twenty-**sided polygon**. The sum of any icosagon’s interior angles is 3240 degrees.

**Is a cube a polygon?**

A **cube** is not a **polygon**. **Polygons** are flat, plane figures. A **cube** is a 3- di mensional solid figure.

**Is a cross a polygon?**

A **polygon** is a closed figure, formed by segments, and its sides do not **cross**.

**What are the 20 polygons?**

**Polygons** are many-sided figures, with sides that are line segments. **Polygons** are named according to the number of sides and angles they have. The most familiar **polygons** are the triangle, the **rectangle**, and the square. A regular **polygon** is one that has equal sides.

**What is a unique polygon?**

In geometry, an octagon (from the Greek ?κτάγωνον 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.

**What is a 30 sided shape called?**

In geometry, a triacontagon or **30**-gon is a thirty-**sided polygon**. The sum of any triacontagon’s interior angles is 5040 degrees.

**What is not a polygon?**

An irregular **polygon** is any **polygon** that is **not** a regular **polygon**. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave **polygons** are irregular since the interior angles cannot all be the same.
