Understanding Polygon Angle Sum
The sum of the interior angles of a polygon is the total of all angles inside the polygon. This sum depends on the number of sides the polygon has.
For any polygon with n sides, the formula to calculate the sum of interior angles is:
For example, a triangle (3 sides) has an interior angle sum of (3-2) * 180° = 180°. A quadrilateral (4 sides) has an interior angle sum of (4-2) * 180° = 360°.
This calculator helps you quickly find the sum of interior angles for any polygon, making geometry calculations easier and more intuitive. Use it to check your homework, explore different polygons, or simply learn more about geometry!
