The area of an heptagon = 11
Calculate side, perimeter
Calculate side:
A = 7/4s2cot(180°/7)
| s2 = | 4A |
| 7cot(180°/7) |
| s2 = | 4 x 11 |
| 7cot(25.714285714286) |
| s2 = | 44 |
| 7 x 2.0765213992964 |
| s2 = | 44 |
| 14.535649795075 |
s2 = 3.0270404571048
s = √3.0270404571048
s = 1.7398392043821
Calculate Perimeter:
P = 7 x side
P = 7 x 1.7398392043821
P = 12.178874430674
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
