Ma kēia ʻatikala, e noʻonoʻo mākou i ka wehewehe a me nā waiwai o kahi huinakolu kaulike (maʻamau). E kālailai pū mākou i kekahi laʻana o ka hoʻoponopono ʻana i kahi pilikia e hoʻohui i nā mea manaʻo.
Wehewehe o ka huinakolu like
Kahi i kūlike (ai ole pololei) ua kapaia he huinakolu i like ka loa o na aoao a pau. ʻO kēlā mau. AB = BC = AC.
'Ōlelo Aʻo: ʻO ka polygon maʻamau he polygon convex me nā ʻaoʻao like a me nā kihi ma waena o lākou.
Nā waiwai o ka huinakolu kaulike
Waiwai 1
Ma ka huinakolu kaulike, he 60° na huina a pau. ʻO kēlā mau mea. α = β = γ = 60°.
Waiwai 2
I loko o ka huinakolu kaulike, ʻo ke kiʻekiʻe i kaha ʻia i kēlā ʻaoʻao kēia ʻaoʻao, ʻo ia ka ʻaoʻao ʻelua o ka ʻaoʻao kahi i kaha ʻia ai, a me ka median a me ka ʻaoʻao ʻelua.
CD – ka waena waena, ke kiʻekiʻe a me ka ʻaoʻao ʻaoʻao AB, a me ka huina huinahalike ACB.
- CD pihi AB => ∠ADC = ∠BDC = 90°
- AD = DB
- ∠ACD = ∠DCB = 30°
Waiwai 3
I loko o ka huinakolu like, ʻo nā ʻāpana ʻāpana, waena, kiʻekiʻe a me nā ʻāpana ʻāpana kū pololei i kaha ʻia i nā ʻaoʻao a pau e hui i kahi kiko.
Waiwai 4
Kūlike nā kikowaena o nā pōʻai i kākau ʻia a puni i kahi huinakolu kaulike a aia ma ka hui ʻana o nā waena, kiʻekiʻe, nā ʻāpana ʻāpana a me nā ʻāpana ʻāpana kū pololei.
Waiwai 5
ʻO ka radius o ka pōʻai i hoʻopuni ʻia a puni ka huinakolu kaulike he 2 manawa o ka radius o ka pōʻai i kākau ʻia.
- R ʻo ia ka radius o ka pōʻai puni;
- r ʻo ia ka radius o ka pōʻai i kākau ʻia;
- R = 2r.
Waiwai 6
I loko o ka huinakolu like, me ka ʻike i ka lōʻihi o ka ʻaoʻao (e lawe mākou iā ia ma ke ʻano he "I"), hiki iā mākou ke helu:
1. Kiʻekiʻe/median/bisector:
2. Puka o ka pōʻai i kākau ʻia:
3. Puke o ka poai puni:
4. Anapuni:
5. ʻĀpana:
Laʻana o kahi pilikia
Hāʻawi ʻia kahi huinakolu kaulike, ʻo 7 knm ka ʻaoʻao. E huli i ka radius o ka pōʻai i hoʻopaʻa ʻia a i kākau ʻia, a me ke kiʻekiʻe o ke kiʻi.

Hoʻohana mākou i nā ʻōkuhi i hāʻawi ʻia ma luna nei e ʻike i nā nui ʻike ʻole ʻia:
