Irregular Polygon Nasıl Hesaplanır?
learn.whatIsHeading
Calculates irregular polygon area using coordinate vertices. Handles non-regular multi-sided shapes.
Formül
Shoelace formula: A = |Σ(x_i × y_(i+1) - x_(i+1) × y_i)| / 2
- A
- |Σ(x_i × y_(i+1) - x_(i+1) × y_i)| / 2 — |Σ(x_i × y_(i+1) - x_(i+1) × y_i)| / 2

Sık sorulan sorular
What's the Shoelace formula?
Calculates area from vertex coordinates; works for any polygon shape.
Does order of vertices matter?
Yes; consistent clockwise or counter-clockwise required; opposite order gives negative area.
