The interior angles of a 20 sided polygon add up to 3240 degrees
Icosagon is the TWENTY-sided Polygon ...... The sum of its interior angles = 3240 degrees
To find the sum of interior angles for any N-sided polygon = N*180° - 360°Solve the equation: N*180° - 360° = 3240°, for N, and N = 20, so a 20 sided polygon will have sum of interior angles = 3240°, and if it is a regular polygon, then each angle = 162°
The sum of the interior angles of a regular polygon can be calculated using the formula (n-2) * 180, where n is the number of sides. For a regular 20-sided polygon, the sum of the interior angles would be (20-2) * 180 = 3240 degrees.
An icosagon is a 20 sided polygon and its interior angles add up to 3240 degrees
