Example: Find the number of diagonals in a decagon. Solution: The number of sides in a decagon is n = 10. The number of diagonals of a decagon is calculated using the formula: n(n - 3)/2 = 10(10 - 3)/2 = 10(7)/2 = 70/2 = 35 Therefore, the number of diagonals of a de...
This is the same regardless of how many sides the polygon has. The exterior angles of a triangle add up to 360°; the exterior angles of a decagon also add up to 360°. Exterior Angle Sum of a Polygon = 360 degrees Suggested Reading ...
