Frequently Asked Questions
What is a dodecagon?
A dodecagon is a 12-sided polygon. A regular dodecagon has all 12 sides and all 12 interior angles equal.
How is dodecagon area calculated?
The regular polygon area formula gives approximately 11.196 times the side length squared for a dodecagon, equivalent to 3 times 2 plus the square root of 3.
What is the interior angle of a regular dodecagon?
Each interior angle is 150 degrees, found from (n minus 2) times 180 divided by n, with n equal to 12.
