The side of an heptagon = 5

Calculate perimeter, area

Calculate Perimeter:

P = 7 x side

P = 7 x 5

P = 35

Calculate Area:

A = 7/4s2cot(180°/7)

A = 7/4(5)2cot(25.714285714286)

A = 7/4(25)cot(25.714285714286)

A = 43.75 x 2.0765213992964

A = 90.84781121922

Calculate Sum of the Interior Angles:

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

Interior Angle Sum = (7 - 2) x 180°

Interior Angle Sum = 5 x 180°

Interior Angle sum = 900°

Calculate polygon diagonals
Diagonals  =  n(n - 3)
  2

Diagonals  =  7(7 - 3)
  2

Diagonals  =  7(4)
  2

Diagonals  =  28
  2

Diagonals = 14

Calculate 1 vertex diagonals:

1 vertex Diagonals = n - 3

1 vertex Diagonals = 7 - 3

1 vertex Diagonals = 4

Calculate triangles from one vertex:

Triangles = N - 2

Triangles = 7 - 2

Triangles = 5

Other Properties:

Sides (Edges) = 7

Faces = 1

Vertices = 7
