Nonagons.
They are called Enneahedrons or nonahedrons.
There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
from there sides
Shapes having less than 4 sides or more than 4 sides are not parallelograms

2D - Nonagon 3D - Nonahedron
nonagon true but is there anymore shapes that have 9 sides?
They are called Enneahedrons or nonahedrons.
The shapes would be around 9 and 8 sides in total.
They are the boundaries of the shapes.
Shapes that have four sides are known as quadrilaterals.
Shapes with straight sides are called polygons
All shapes have sides. Including a circle which has one curved side.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
