Frequently Asked Questions
What is the general regular polygon area formula?
Area equals the number of sides times the side length squared, divided by 4 times the tangent of pi divided by the number of sides. This single formula works for any regular polygon, from a triangle to a 100-sided shape.
How does this compare to the individually named polygon calculators?
It is the exact same underlying formula, just parametrized by number of sides instead of being fixed to one specific polygon name like hexagon or octagon.
Does this work for an irregular polygon?
No, this assumes all sides and angles are equal. An irregular polygon's area needs to be calculated from its vertex coordinates instead, for example with the shoelace formula.
