A seven-sided shape is called a heptagon. A heptagon is one type of polygon, which can have any number of sides.
Know MoreA polygon is defined as a two-dimensional or plane figure that consists of line segments, which are called edges or sides. The points at which the segments meet are called vertices or corners. Additionally, only two sides meet at each corner of a polygon.
There are five types of polygons:
A seven-sided polygon is called a heptagon. Polygon names are derived from the Greek language and are formed by using a prefix based on the Greek and adding it to the suffix "gon."
Polygons can have nearly an infinite number of sides, where the letter n represents the number of sides and the word is written "n-gon." For example, a polygon with 47 sides would be written as 47-gon. Another naming convention for polygons with more than 20 sides involves using the Greek prefix for the tens digit, plus "kai," which is the Greek for "and," plus the single digit, and finally the suffix "gon," which would make a 47-sided polygon a tetracontakaiheptagon.

Full Answer >A 12-sided shape is called a dodecagon. A dodecagon is a type of polygon, which is a two-dimensional shape comprised of straight lines. These lines connect to each other to form a closed shape.
Full Answer >An 11-sided polygon is called a hendecagon. It is also known as the undecagon or unidecagon. However, the term "hendecagon" takes precedence over these variants because of its consistency in using a Greek prefix and suffix, instead of combining a Roman prefix with a Greek suffix.
