What’s a shape with 9 sides called?
All of these polygons have different properties based on the number of sides and angles they have. A nonagon is a nine sided polygon and it is also called an Enneagon or 9-gon. In other words, a nonagon is a nine sided closed two dimensional figure.
What is a shape with 7 sides called?
A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning "seven") with the Greek suffix -gon (from gonia, meaning "angle"), and is therefore not recommended.

What is a shape with 8 sides called?
An octagon is a shape with 8 sides and 8 angles.
What does a nonagon look like?
A regular nonagon shape is a 9-sided polygon that has all nine sides and nine angles congruent. Congruent sides have the same length and congruent angles have the same measure. An irregular nonagon shape is a 9-sided polygon that has at least one side and at least one angle that is not congruent to the others.
What is not a polygon?
Polygons may have any number of sides. A shape with curved sides is not a polygon. A shape that is not fully closed is not a polygon.

Is a diamond a polygon?
We can conclude that though all diamonds are polygons, not all polygons are diamonds. A square is a quadrilateral. Furthermore, a square has all of its sides of equal length, and since all of its angles have the same measure, opposite angles have the same measure, and opposite sides are parallel.

Is Moon a polygon?
As the definition tells us, a polygon's sides must be straight. If any side is curved, then it's no longer a polygon. So, the moon, the sun and rainbows are not polygons because they are curved. Also, if you draw a shape and your end point is not the same as your start point, then you don't have a polygon either.
