Ma kēia paʻi ʻana, e noʻonoʻo mākou i nā waiwai kumu o ke kiʻekiʻe i loko o kahi huinakolu kaulike (maʻamau). E nānā pū mākou i kahi laʻana o ka hoʻoponopono ʻana i kahi pilikia ma kēia kumuhana.
'Ōlelo Aʻo: kapaia ka huinakolu kaulikeina ua like kona mau aoao a pau.
Nā waiwai kiʻekiʻe ma ka huinakolu kaulike
Waiwai 1
ʻO kēlā me kēia kiʻekiʻe i loko o ka huinakolu kaulike, ʻo ia ka mahele ʻelua, ka waena, a me ka ʻaoʻao ʻokoʻa.
- BD – hoʻohaʻahaʻa ʻia ke kiʻekiʻe i ka ʻaoʻao AC;
- BD ʻo ia ka median e māhele ai i ka ʻaoʻao AC i ka hapalua, ie AD = DC;
- BD – huina huinahalike ABC, ie ∠ABD = ∠CBD;
- BD ka median perpendicular to AC.
Waiwai 2
Ua like ka lōʻihi o nā kiʻekiʻe ʻekolu o ka huinakolu kaulike.
AE = BD = CF
Waiwai 3
Ua māhele ʻia nā kiʻekiʻe o ka huinakolu like ma ka orthocenter (kahi o ka hui ʻana) i ka ratio o 2:1, e helu ana mai ka piko mai kahi i huki ʻia ai lākou.
- AO = 2OE
- BO = 2OD
- CO = 2OF
Waiwai 4
ʻO ke kikowaena o ka huinakolu kaulike ke kikowaena o nā pōʻai i kahakaha ʻia a puni.
- R ʻo ia ka radius o ka pōʻai puni;
- r ʻo ia ka radius o ka pōʻai i kākau ʻia;
- R = 2r (ma hope mai Waiwai 3).
Waiwai 5
ʻO ke kiʻekiʻe o ka huinakolu kaulike e puʻunaue iā ia i ʻelua huinakolu ʻokoʻa ʻokoʻa.
S1 =S2
ʻEkolu mau kiʻekiʻe o ka huinakolu kaulike e puʻunaue iā ia i 6 mau huinakolu ʻākau o ka ʻāpana like.
Waiwai 6
I ka ʻike ʻana i ka lōʻihi o ka ʻaoʻao o ka huinakolu kaulike, hiki ke helu ʻia kona kiʻekiʻe e ke kumu:
a ka aoao o ka huinakolu.
Laʻana o kahi pilikia
ʻO ka radius o ka pōʻai i hoʻopuni ʻia a puni ka huinakolu kaulike he 7 knm. E imi i ka aoao o keia huinakolu.
pāʻoihana
E like me kā mākou ʻike mai waiwai 3 и 4, ʻo ka radius o ka pōʻai pōʻai he 2/3 o ke kiʻekiʻe o kahi huinakolu kaulike (h). No laila, h = 7 ∶ 2 ⋅ 3 = 10,5 knm.
I kēia manawa, e hoʻomau i ka helu ʻana i ka lōʻihi o ka ʻaoʻao o ka huinakolu (ua loaʻa ka ʻōlelo mai ke kumu ma Waiwai 6):
