A five-sided shape is called a pentagon. A six-sided shape is a hexagon , a seven-sided shape a heptagon, while an octagon has eight sides... The names of polygons are derived from the prefixes of ancient Greek numbers.

A polygon is a flat two-dimensional shape with straight sides that are fully closed . The sides must be straight, not curved. However, polygons can have any number of sides. The word polygon comes from the Greek “polugonos”. ... This is because a polygon has many different angles and corners within its shape.
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon.
A six-sided shape is a hexagon , a seven-sided shape a heptagon
In geometry, a hectogon or hecatontagon or 100-gon is a hundred-sided polygon.
A 13-sided polygon, sometimes also called the triskaidecagon.
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
In geometry, a heptagon is a seven-sided polygon or 7-gon.

More than Four Sides. In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon.
In geometry, a tetradecagon or tetrakaidecagon or 14-gon is a fourteen-sided polygon.

In geometry, a pentacontagon or pentecontagon or 50-gon is a fifty-sided polygon. The sum of any pentacontagon’s interior angles is 8640 degrees. A regular pentacontagon is represented by Schläfli symbol {50} and can be constructed as a quasiregular truncated icosipentagon, t{25}, which alternates two types of edges.
In geometry, a pentadecagon or pentakaidecagon or 15-gon is a fifteen-sided polygon.
