Dodecagon Calculator

MATH CALCULATOR Dodecagon Calculator Calculate the area, perimeter, and interior angles of a dodecagon with ease using our online calculator.
📖
What is the Dodecagon Calculator & How does it work?
A dodecagon is a polygon with twelve sides. The properties of a regular dodecagon (where all sides and angles are equal) can be calculated using specific formulas.
Area = 3 times (2 + sqrt{3}) times s^2
s = side length
The perimeter of a regular dodecagon is simply the sum of its twelve equal sides, which can be calculated as:
Perimeter = 12 times s
s = side length
Each interior angle of a regular dodecagon can be calculated using the formula:
Interior Angle = frac{(n-2) times 180}{n}
n = number of sides (12 for a dodecagon)

Frequently Asked Questions
How do I calculate the area of a regular dodecagon?
To find the area, use the formula: Area = 3 × (2 + √3) × s², where s is the side length.
What is the perimeter of a regular dodecagon?
The perimeter is calculated as Perimeter = 12 × s, with s being the side length.
How do I find each interior angle of a regular dodecagon?
Use the formula Interior Angle = (n-2) × 180/n, where n is the number of sides (12 for a dodecagon).
What are the properties of a regular dodecagon?
A regular dodecagon has twelve equal sides and angles. Each interior angle measures 150 degrees, and the sum of its interior angles is 1800 degrees.
Can this calculator handle irregular dodecagons?
This calculator is specifically for regular dodecagons where all sides and angles are equal. For irregular dodecagons, different calculations are needed.
