Triangles, squares, rectangles, pentagons, hexagons and octagons are some of the most common polygons. A polygon is a plane figure with many sides made up of line segments.

The name of a 10-sided polygon is a decagon. The term "decagon" comes from the modern Latin word "decagonum" and from the Greek "dekagonon," which is a combination of "deka," meaning "ten" and "gonia," meaning "corner" or "angle."

The accepted name of a 12-sided polygon is "dodecagon." A polygon is a two-dimensional shape consisting of angles and straight lines in a closed system. The word "polygon" comes from the Greek "poly," which means "many" and "gon," which means "sides."

The different types of polygons include convex, concave, regular, irregular, simple or complex. Polygons will have half of these qualities.

An 11-sided polygon is called a hendecagon. In order for an 11-sided shape to be considered a hendecagon, its sides must all be straight and form a closed shape.

A five-sided polygon is called a pentagon. A pentagon also has five vertices and five interior angles, which add up to a total of 540 degrees.

A polygon is identified based on the number of its sides and vertices. Polygons are made of straight lines, called edges or sides, that meet in corners to form a closed circuit. The least number of sides needed to form a closed loop is three. A three-sided polygon is called a triangle. The list of c

The polygon with 1,000 sides, 1,000 vertices and 1,000 angles is called a chiliagon or a 1,000-gon. The term "chiliagon," with a Greek-derived prefix meaning “thousand,” is a proposed name for the 1,000-sided, two-dimensional shape, but it is seldom used.
