Formula

To ensure clarity and utility, the calculator operates on a straightforward mathematical formula:

Exterior Angle = 360 / Number of Sides

Where:

  • Exterior Angle is the measure of the angle form outside the polygon.
  • Number of Sides is the total number of sides in the polygon.

This formula is derived from the principle that the sum of the exterior angles of any polygon equals 360 degrees, a fundamental concept in geometry.
