nonagon true but is there anymore shapes that have 9 sides?
The shapes would be around 9 and 8 sides in total.
The names of shapes based on the number of sides up to 10 are as follows: Triangle (3 sides) Quadrilateral (4 sides) Pentagon (5 sides) Hexagon (6 sides) Heptagon (7 sides) Octagon (8 sides) Nonagon (9 sides) Decagon (10 sides)
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.
There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
