Nonagon area = 6

Nonagon area = 6

Enter nonagon info:

The area of a nonagon is 6

Calculate side, perimeter

Calculate side:

A = 9/4s2cot(180°/9)

s2  =	4A
	9cot(180°/9)

s2  =	4 x 6
	9cot(20)

s2  =	24
	9 x 2.7474774228644

s2  =	24
	24.727296805779

s2 = 0.97058729017199

s = √0.97058729017199

s = 0.98518388647602

Calculate Perimeter:

P = 9 x side

P = 9 x 0.98518388647602

P = 8.8666549782842

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
