Regular heptadecagon

All sides of a regular heptadecagon are the same length. Each corner is 158.82°. All corners added together equal 2700°.

The amount of space a regular heptadecagon takes up is

The area of a regular heptadecagon of side length a is given by

A = \frac{17}{4} a^{2} \cot \frac{π}{17} ≃ 22, 735 a^{2}

The regular heptadecagon edit geometry compass and ruler in 1796, demonstrated Carl Friedrich Gauss.

This is due to Göttingen of a memorial statue of a regular heptadecagon pedestal.
