Exterior Angle of a Polygon
This tool helps you quickly find the measure of a single exterior angle for any regular polygon. Just enter the number of sides, and we'll do the math for you. Remember, the sum of all exterior angles for any convex polygon is always 360 degrees!
Enter an integer greater than 2 for a polygon.
This tool helps you quickly find the measure of a single exterior angle for any regular polygon. Just enter the number of sides, and we'll do the math for you. Remember, the sum of all exterior angles for any convex polygon is always 360 degrees!
For a Regular Polygon: Each Exterior Angle = 360° / n Where 'n' is the number of sides.
To find the exterior angle of a regular hexagon, which has 6 sides: Exterior Angle = 360° / 6 = 60° So, each exterior angle of a regular hexagon measures 60 degrees.
An exterior angle of a polygon is formed by extending one of its sides and the adjacent side. It's the angle between the extended side and the next side of the polygon.
Imagine walking around the perimeter of any convex polygon. At each vertex, you turn by the measure of the exterior angle. By the time you complete one full circuit and return to your starting point, you will have made one full 360-degree turn. This holds true for any convex polygon, regular or irregular.
This calculator is specifically designed for regular polygons, where all exterior angles are equal. For irregular polygons, the individual exterior angles will vary, but their sum will still be 360 degrees.
