Regular Polygon Properties Calculator
Calculate area, perimeter, interior angles, and other properties of regular polygons
About this calculator
The Regular Polygon Properties Calculator is a comprehensive tool that computes essential geometric properties of any regular polygon, including area, perimeter, interior angles, exterior angles, and apothem length. This calculator is invaluable for students, architects, engineers, and designers working with geometric shapes in construction, art, or mathematical applications. Simply input the number of sides and one known measurement to instantly calculate all related properties, making complex polygon calculations effortless and accurate.
How to use
Enter the number of sides of your regular polygon and provide one known measurement (such as side length, radius, or apothem). Select your preferred units and click calculate. The tool will instantly display all polygon properties including area, perimeter, interior angles, exterior angles, and other geometric measurements.
Frequently asked questions
What is the difference between circumradius and inradius?
Circumradius is the distance from center to vertex, while inradius (apothem) is the distance from center to the middle of a side.
Can I calculate properties for irregular polygons?
No, this calculator only works for regular polygons where all sides and angles are equal.
What's the minimum number of sides for a polygon?
A polygon must have at least 3 sides. Common examples include triangles, squares, pentagons, and hexagons.
