The internal angle sum of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a polygon with 20 sides, the calculation would be ( (20 - 2) \times 180^\circ = 18 \times 180^\circ = 3240^\circ ). Therefore, the internal angle sum of a polygon with 20 sides is 3240 degrees.
The polygon would have 10 sides.
no polygon can have its angle sum be 1660 degrees. the closest shape would be a 11 sides shape
The sum of all the internal angles of a polygon with n sides is 180*(n-2) degrees. In a regula polygon, therefore, each internal angle is 180*(n-2)/n degrees. Also The sum of all the external angles in 360 degrees. The sum of each external angle in a regular polygon is 360/n degrees.
A polygon with internal angles of 144 degrees is a dodecagon, which has 12 sides. In this case, each internal angle measures 144 degrees, and the sum of the internal angles for a dodecagon is 1,440 degrees (calculated as (12-2) × 180). This type of polygon can be regular if all sides and angles are equal.
The sum of the internal angles of a polygon of n sides is (n-2)*180 degrees.
sum of internal angles = 180(n-2) where n is the total number of sides of the polygon.
