A polygon can be any number of shapes. A polygon is a two dimensional shape made of at least 3 straight lines that do not cross and is a closed shape. Examples of polygons would include triangles, squares, rectangles, hexagons, and octagons.


A pentagon is a five-sided polygon with two right angles. This is true only if all sides are not equal or congruent, which allows the pentagon to have two right angles. The sides of a regular pentagon are equal in size, which disallows the presence of right angles.


A polygon with four sides and four angles is called a quadrilateral. Quadrilaterals are two-dimensional, closed shapes with angle measurements that add up to 360 degrees.


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.


Hexagons are polygons with six sides (or edges) and six angles (or vertices). They are classified as regular or irregular, as well as convex or concave.


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.
