The interior angles of a 19 sided polygon add up to 3060 degrees
Chat with our AI personalities
The sum of the exterior angles of any polygon is always 360 degrees. In a 19-sided polygon, each exterior angle would be 360/19 = 18.9474 degrees. Therefore, the sum of the exterior angles of a 19-sided polygon would be 19 * 18.9474 = 360 degrees.
An individual angle can have any size you like. The only constraint is on the sum of all 19 angles.
