In geometry, a regular decagon (also called a regular decagon or regular decagon) or 11-sided polygon is Eleven-sided polygon(The name hendecagon comes from the Greek hendeka « eleven » and –gon « horn », and is often preferred over the hybrid decagon, the first part of which consists of the Latin undecim « eleven ».)

What is a decagon?

An 11-sided polygon is an 11-sided polygon, also known as an decagon or an eldecagon.

Are there 2-sided polygons?

In geometry, a number is a polygon with two edges (edges) and two vertices. Its construction is degenerate in the Euclidean plane, since either the two sides coincide or one or both sides must be curved; however, it can be easily visualized in elliptical space.

Is the circle 2D or 3D?

2D shapes have only 2 dimensions and are flat, such as square, rectangle, triangle, circle, pentagon, hexagon, heptagon, octagon, nonagon, decagon, parallelogram, rhombus, Kite, Quad, Trapezoid. 3D objects have three dimensions. The planes (faces) of many 3D objects consist of 2D shapes, such as
