Nonagons.
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.
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
