Decagon side = 16
Enter Decagon Info Below
The side of an decagon is 16
Calculate perimeter, area
Calculate Perimeter:
P = 10 x side
P = 10 x 16
P = 160
Calculate Area:
A = 5/2s2√5 + 2√5
A = 2.5(16)2(3.0776835371753)
A = 2.5(256)(3.0776835371753)
A = 1969.7174637922
Calculate Sum of the Interior Angles:
Interior Angle Sum = (sides - 2) x 180°
Interior Angle Sum = (10 - 2) x 180°
Interior Angle Sum = 8 x 180°
Interior Angle sum = 1440°
Calculate decagon diagonals
| Diagonals = | n(n - 3) |
| 2 |
| Diagonals = | 10(10 - 3) |
| 2 |
| Diagonals = | 10(7) |
| 2 |
| Diagonals = | 70 |
| 2 |
Diagonals = 35
Calculate diagonals from 1 vertex:
1 vertex Diagonals = n - 3
1 vertex Diagonals = 10 - 3
1 vertex Diagonals = 7
Calculate number of Δ from 1 vertex:
Triangles = N - 2
Triangles = 10 - 2
Triangles = 8
