WebApr 12, 2024 · A decagon is one such polygon that has ten sides. In this article, we will explore the properties of a decagon and how it can be constructed. Properties of a Decagon. A decagon is a ten-sided polygon with ten angles. The sum of the interior angles of a decagon is (n-2) x 180 degrees, where n is the number of sides. WebThe 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, …

What is a Diagonal - Meaning, Examples Diagonal Line
WebA regular hexagon contains six congruent sides and six congruent angles. Let’s use what we know to determine other properties. A number of diagonals is: d = n ( n – 3) 2 = 6 ( 6 – 3) 2 = 9. The sum of the measures of all interior angles is: ( n – 2) ⋅ 180 ∘ = 4 ⋅ 180 ∘ = 720 ∘.
