Nonagon perimeter = 8

Nonagon perimeter = 8

Enter nonagon info:

The perimeter of a nonagon is 8

Calculate side, area

Calculate side:

s  =	P
	9

s  =	8
	9

s = 0.88888888888889

Calculate Area:

A = 9/4s2cot(180°/9)

A = 9/4(0.88888888888889)2cot(20)

A = 9/4(0.79012345679012)cot(20)

A = 1.7777777777778 x 2.7474774228644

A = 4.8844043073145

Calculate Sum of the Interior Angles:

Interior Angle Sum = (sides - 2) x 180°

Interior Angle Sum = (9 - 2) x 180°

Interior Angle Sum = 7 x 180°

Interior Angle sum = 1260°

Calculate polygon diagonals

Diagonals  =	n(n - 3)
	2

Diagonals  =	9(9 - 3)
	2

Diagonals  =	9(6)
	2

Diagonals  =	54
	2

Diagonals = 27

Calculate 1 vertex diagonals:

1 vertex Diagonals = n - 3

1 vertex Diagonals = 9 - 3

1 vertex Diagonals = 6

Calculate triangles from one vertex:

Triangles = N - 2

Triangles = 9 - 2

Triangles = 7

Other Properties:

Sides (Edges) = 9

Faces = 1

Vertices = 9
