WebAug 22, 2024 · Number of diagonals in a n-sided polygon = n(n-3)/2 = 10(10 – 3)/2 = 10(7)/2 = 35. Therefore, the value of each internal angle of a regular decagon is 144° the number of diagonals is 35. Example 3: Calculate the sum of interior angles of a hexagon using the polygon formula. Solution: The polygon is a hexagon. So, number of sides (n) = 6. We ... WebThe sides of a regular polygon are the line segments that make it up. Try this Adjust the regular polygon below by dragging any orange dot, or alter the number of sides. The length of the sides will change. The formulas below give the length of the side of regular polygon given the number of sides and either the radius or apothem.
