you call a seven sided shape a heptagon.
An 11 sided shape is an Eptogon
A 0-sided shape is called a nullipore or vacuous shape. It is a theoretical concept in mathematics that represents a point in space with no measurable dimensions. In geometric terms, it is often referred to as a "point" or "vertex." This shape has no sides, angles, or any other defining features beyond its position in space.
A 12-sided shape is called a dodecagon.
A 30 sided shape is called a Triacontagon.
There is no such thing as a 1 sided shape nor a two sided shape.
A nine sided shape or polygon is called a nonagon.
A seven sided shape is called a heptagon.
Why not just call it "a 130-sided shape"? because its not called that, spaz.
A five sided geometric shape is called a pentagon.
