Ma kēia hoʻolaha, e noʻonoʻo mākou i ka wehewehe, nā mea, nā ʻano a me nā waiwai nui o kahi parallelepiped, incl. huinahāhā. Hoʻopili ʻia ka ʻike i hōʻike ʻia me nā kiʻi kiʻi no ka ʻike maikaʻi.
Wehewehe o ka pahu
Parallelpiped he kiʻi geometric ma ke ākea; he hexagon nona na helehelena he mau paralelograms. He 12 mau ʻaoʻao a me 6 mau ʻaoʻao.
ʻO ka parallelepiped kahi ʻano like me ka paralelogram ma ke ʻano he kumu. ʻO nā mea nui o ke kiʻi e like me nā mea o ka prisma.
'Ōlelo Aʻo: Hōʻike ʻia nā ʻōkuhi no ka helu ʻana (no kahi kiʻi ʻehā) a me kahi parallelepiped ma nā puke ʻokoʻa.
Nā ʻano o nā parallelepipeds
- Pololei parallelepiped – ʻo nā ʻaoʻao ʻaoʻao o ke kiʻi e kū pololei i kona mau kumu a he mau ʻāpana ʻehā.
- Hiki i kahi parallelepiped pololei mika'ākau ʻO nā kumu he mau ʻāpana ʻehā.
- Oblique parallelepiped – ʻaʻole kū pololei nā maka ʻaoʻao i nā kumu.
- – he huinaha like na aoao a pau o ke kii.
- Inā he rhombus like nā helehelena a pau o ka parallelepiped, ua kapa ʻia ia rhombohedron.
Nā waiwai pahu
1. Ua like like na helehelena ku e o ka parallelepiped, a he mau huinalike like.
2. ʻO nā diagonal a pau o ka parallelepiped e ʻokoʻa i kekahi kiko a ua māhele ʻia i ka hapalua ma laila.
3. huinahā like diagonal (D) ua like ia me ka huina o na huinahalike o kona mau ana ekolu: ka loa. (a), laula (B) a me ke kiekie (C).
