The name of a 9 sided polygon is Nonagon.
The name of a 9 sided polygon is nonagon or enneagon.
there is 9 planes of symmetry in a cube
Any regular polygon of n sides, has an order of symmetry of n. Therefore, since a nonagon has nine sides, a nonagon has an order of symmetry of 9.
How many lines of symmetry does a original 9 sided shape have
9
Nonagons.
They are nonagons
Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry

I think that it can have 0, 1, 2, 3, 6, 9 or 18 lines of symmetry.
If it's a regular 9 sided nonagon it's capable of 9 lines of symmetry or mirror images
Assume the expression is: y = x² - 6x + 5 Complete the squares to get: y = x² - 6x + 9 + 5 - 9 = (x - 3)² - 4 By the vertex form: y = a(x - h)² + k where x = h is the axis of symmetry x = 3 is the axis of symmetry.
If it's a regular 9 sided nonagon then each interior angle is 140 degrees and they all add up to 1260 degrees
A regular nonagon with 9 sides has a rotational symmetry of 9.
