Ke ʻimi nei i nā ʻāpana - 2
A trapezium he kiʻi ʻehā ʻaoʻao nona hoʻokahi pālua o nā ʻaoʻao like (ʻo nā laina like ma kahi ʻili he mau laina i hui ʻole). A pākaulike he kiʻi ʻehā ʻaoʻao nona nā pālua ʻelua o nā ʻaoʻao like. Ma ka huinakolu nui ma ka hema, aia ʻelima mau huinakolu i hōʻailona ʻia - nā huinakolu kala ʻehā a me ka huinakolu holoʻokoʻa. ʻO ka huinakolu nui like ma waenakonu, aia kekahi o kona mau trapezoid ʻekolu i kala ʻia i ka ʻōmaʻomaʻo. ʻO ka huinakolu nui like ma ka ʻākau, aia kekahi o kona mau parallelogram ʻekolu i kala ʻia i ka ʻulaʻula.
KA PILI
I kēlā me kēia o kēia mau kiʻi, e helu i ka helu o nā huinakolu, nā trapezoids, a me nā parallelograms.
HE ʻAHOLAHA
E hana i nā kiʻi e like me kēia no nā poʻe ʻē aʻe e helu i nā huinakolu a me nā trapezoids.
Notes
KA PILI
E hana ma ka helu hoʻonohonoho me ka hoʻohana ʻana i kēia mau helu ʻelua. Pono ka lua o ka helu akahele.
ʻO ka huinakolu nui ma ka hema:
He 9 mau huinakolu liʻiliʻi (kumu 1), 3 mau huinakolu waena (kumu 2), a me 1 huinakolu nui (kumu 3), no ka huina o 13 mau huinakolu.
He 9 ona trapezoids liʻiliʻi (kumu 2 luna 1), 3 trapezoids waena (kumu 3 luna 2), a me 3 trapezoids nui (kumu 3 luna 1), no ka huina o 15 trapezoids.
He 9 mau parallelogram liʻiliʻi kona (ʻaoʻao 1 a me 1) a me 6 mau parallelogram waena (ʻaoʻao 2 a me 1), no ka huina o 15 mau parallelogram.
ʻO ka huinakolu nui ma ka ʻākau:
ʻO ka huinakolu nui ma ka ʻākau he 16 mau huinakolu liʻiliʻi (kumu 1), 7 mau huinakolu waena liʻiliʻi (kumu 2), 3 mau huinakolu waena nui (kumu 3), a me 1 huinakolu nui (kumu 4), no ka huina o 27 mau huinakolu.
He 18 ona trapezoids liʻiliʻi (kumu 2 luna 1), 9 trapezoids liʻiliʻi lōʻihi aʻe (kumu 3 luna 2), 3 trapezoids liʻiliʻi lōʻihi loa (kumu 4 luna 3), 9 trapezoids waena (kumu 3 luna 1), 3 trapezoids waena lōʻihi aʻe (kumu 4 luna 2), a me 3 trapezoids nui (kumu 4 luna 1), no ka huina o 18 + 9 + 3 + 9 + 3 + 3 = 45 trapezoids.
He 18 mau parallelogram liʻiliʻi kona (ʻaoʻao 1 a me 1), 18 mau parallelogram liʻiliʻi lōʻihi (ʻaoʻao 2 a me 1), 6 mau parallelogram liʻiliʻi lōʻihi (ʻaoʻao 3 a me 1), a me 3 mau parallelogram waena (ʻaoʻao 2 a me 2), no ka huina o 18 + 18 + 6 + 3 = 45 mau parallelogram.
