Te Ka-aua

Ko tangiraki ba kona korea am arc tangent teuana ae e taraa n babakoia uoua circles are e bon tii touch te circles n te point of contacts.

Ana radius te circle ae bubura 'A' : 30mm

Ana radius te circle ane uarereke riki 'B' : 25mm

Ana radius te arc tangent 'C' : 120mm

Karaoana:

1. Korei am circles akana uoua ao abakin te maranga i marenaiia e na aki raka i aon 5omm.

2. Anaa te radius 'A' ao minus man ana radius te arc tangent 'C': (120-30=90)

3. Kabonganaa ana center circle 'A' ao kaurea am compass nakon 90 ao korea am arc i aan te circles

4. Manga anaa radius 'B' ao minus man ana radius te arc tangent 'C': (120-25=95)

5. Kabonganaa ana center circle 'B' ao kaurea am compass nakon 95ao korea am arc ba e na intersect ba te moan arc (man step 3)

6. Ana intersect arcs aikai n point 'C'

7. Tomaa point 'C' ma ana centre te circle anne bubura ao reitianako nakon te circumference are iterana (E).

8. Ao tomaa point 'C' ma ana centre te circle anne uarereke ao reianako nakon te circumference are iterana. (F)

9. Kabonganaa point 'C' ba am centre ao kaurea am compass nakon E ke F. Kabonganaa ba am radius ao katurua am arc tangent man E nakon F.

Kauoua n itera

Manga katea am arc tangent ae e na biri i aan taian circles. Ngkana e tia am tamnei ao e na  katootoonga te tamnei ae i nano.
