Ocogon

Ocogon sen figura har oco comen, oco gono ji oco tyan.

Weylungoje
Weylungoje de pimpan ocogan har comenli lungoje a sen:
 * $$\text{Weylungoje} = 8a.$$

Peryaje
Peryaje de pimpan ocogon har comenli lungoje a sen:


 * $$\text{Peryaje} = 2a^2(1 + \sqrt{2}).$$

Inli gono
Inli gono de pimpan ocogon maxuscu cel 1080°:

(n - 2) \times 180^\circ \\ = (8 - 2) \times 180^\circ \\ = 6 \times 180^\circ \\ = 1080^\circ, $$

ji moyun sen 135°:

\begin{align} \text{Inli gono} & = \frac{(n - 2) \times 180^\circ}{n} \\ & = \frac{(8 - 2) \times 180^\circ}{8} \\ & = \frac{6 \times 180^\circ}{8} \\ & = \frac{1080^\circ}{8} \\ & = 135^\circ. \end{align} $$

Exli gono
Moy exli gono de ocogon sen 45° ji maxuscu cel 360°:

45^\circ \times n \\ = 45^\circ \times 8 \\ = 360^\circ. $$

Gonolinku
Ocogon hare 20 gonolinku:

\begin{align} \text{Gonolinku} & = \frac{n(n - 3)}{2} \\ & = \frac{8(8 - 3)}{2} \\ & = \frac{8(5)}{2} \\ & = \frac{40}{2} \\ & = 20, \end{align} $$

ji fe pimpan ocogon, lungoje de moy gonolinku har comenli lungoje a sen:
 * $$\text{Lungoje} = a\sqrt{4 + 2\sqrt{2}}.$$
