What Is the Polygon Interior Angle Calculator?
A polygon interior angle calculator determines angular sums and symmetry properties for planar convex polygons.
How Does the Polygon Interior Angle Calculator Work?
Decomposes n-gons into internal triangular partitions and derives complementary exterior rotations.
Polygon Interior Angle Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
Sum = (n - 2) × 180° · Each = (n - 2) × 180° ÷ n · Diagonals = n(n - 3) ÷ 2
Triangulates the polygon from a single vertex into (n - 2) triangles and divides equally for regular equiangular polygons.
