The perimeter of an heptagon = 2
Calculate side, area
Calculate side:
| s = | P |
| 7 |
| s = | 2 |
| 7 |
s = 0.28571428571429
Calculate Area:
A = 7/4s2cot(180°/7)
A = 7/4(0.28571428571429)2cot(25.714285714286)
A = 7/4(0.081632653061224)cot(25.714285714286)
A = 0.14285714285714 x 2.0765213992964
A = 0.29664591418521
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
