Ma kēia hoʻolaha, e noʻonoʻo mākou i nā waiwai nui o kahi prism (e pili ana i nā kumu, nā ʻaoʻao ʻaoʻao, nā alo a me ke kiʻekiʻe), e hele pū me lākou me nā kiʻi kiʻi no ka ʻike maikaʻi ʻana i ka ʻike i hōʻike ʻia.
'Ōlelo Aʻo: ua nānā mākou i ka wehewehe ʻana o kahi prism, kāna mau mea nui, nā ʻano like ʻole a me nā koho cross-section, no laila ʻaʻole mākou e noʻonoʻo pono iā lākou ma aneʻi.
Na Waiwai Prisma
E noʻonoʻo mākou i nā waiwai me ka hoʻohana ʻana i ka laʻana o kahi prisma pololei hexagonal, akā pili lākou i nā ʻano kiʻi ʻē aʻe.
Waiwai 1
ʻElua kumu like o ka prisma, he polygons.
ʻO kēlā mau mea. ABCDEF = A1B1C1D1E1F1
Waiwai 2
ʻO nā ʻaoʻao ʻaoʻao o kēlā me kēia prisma he paralelograms.
Aia ma ke kiʻi ma luna: AA1B1B, BB1C1C, CC1D1D, DD1E1E, EE1F1F и AA1F1F.
Waiwai 3
ʻO nā ʻaoʻao ʻaoʻao a pau o ka prisma ua ʻano like a like.
- AA1 = BB1 = CC1 = DD1 = EE1 = FF1
- AA1 || BB1 || CC1 || DD1 || EE1 || FF1
Waiwai 4
Aia ka ʻāpana kū pololei o ka prisma ma nā kihi ʻākau i nā ʻaoʻao āpau a me nā ʻaoʻao o ke kiʻi.
Waiwai 5
kiʻekiʻe (h) o kekahi prisma i hili i na manawa a pau, emi mai ka loa o kona lihi aoao. A ua like ke kiekie o kekahi kii pololei me kona kae.
- Ma ka fig. hema: h = AA1
- Ma ka fig. hihia: h < AA1
