Na obrázku je pravidelný štvorboký ihlan so štvorcovou podstavou s hranou
\(a = 4\; \mathrm{cm}\) s telesovou
výškou \(v = 6\; \mathrm{cm}\).
Pre veľkosť vyznačené odchýlky platí:
\(\mathop{\mathrm{tg}}\nolimits \frac{\varphi }
{2} = \frac{2}
{2\sqrt{10}}\mathrel{\implies }\varphi \mathop{\mathop{\doteq }}\nolimits 35^{\circ }6^{\prime}\)
\(\mathop{\mathrm{tg}}\nolimits \varphi = \frac{6}
{2\sqrt{2}}\mathrel{\implies }\varphi \mathop{\mathop{\doteq }}\nolimits 64^{\circ }46^{\prime}\)
\(\mathop{\mathrm{tg}}\nolimits \frac{\varphi }
{2} = \frac{2}
{6}\mathrel{\implies }\varphi \mathop{\mathop{\doteq }}\nolimits 36^{\circ }52^{\prime}\)
\(\mathop{\mathrm{tg}}\nolimits \frac{\varphi }
{2} = \frac{2\sqrt{2}}
{6} \mathrel{\implies }\varphi \mathop{\mathop{\doteq }}\nolimits 50^{\circ }29^{\prime}\)
