Ngā Upane mō te Whakaoti Whārite Rārangi

Whakangāwaritia te tauraro o \frac{2}{\sqrt{2}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{2}.

$$2R=4\times \frac{2\sqrt{2}}{\left(\sqrt{2}\right)^{2}}$$

Ko te pūrua o \sqrt{2} ko 2.

$$2R=4\times \frac{2\sqrt{2}}{2}$$

Me whakakore te 2 me te 2.

$$2R=4\sqrt{2}$$

Whakawehea ngā taha e rua ki te 2.

$$\frac{2R}{2}=\frac{4\sqrt{2}}{2}$$

Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.

$$R=\frac{4\sqrt{2}}{2}$$

Whakawehe 4\sqrt{2} ki te 2.

$$R=2\sqrt{2}$$
