Mahino ki he Ngaahi Tapatefa
Ko e ngaahi tapatefa ko ha ngaahi hala fakalilifu ʻoku tafaʻaki ʻa e ngaahi meʻa loli mo e ngaahi meʻa tapafā, ʻo fakahoko ʻa e ngaahi tuliki feōmi kae vahevahe ʻa e ngaahi fōtunga ki ha tapatolu tapafā tatau ʻe ua. Tatau ai pe pe ʻoku ke ngāue mo ha meʻa loli, ha meʻa tapafā, pe ko ha fōtunga ʻoku ʻi ai ha tapatolu tuliki tapafā, ʻoku mahuʻinga hoʻo mahino ki he ngaahi tapatefa.
Ngaahi Fakakaukau Mahuʻinga
Ngaahi Meʻa Loli mo e Ngaahi Meʻa Tapafā
Ko ha meʻa loli ko ha fōtunga tafaʻaki fā mo e ngaahi tafaʻaki feōmi ʻoku tatau ʻi he loloa ka ʻoku ʻikai fakapapauʻi ʻoku tatau kotoa ia. ʻOku ʻi ai hono tapatefa ʻe ua, pea ko e taki taha ʻoku tafaʻaki ʻa e meʻa loli ki ha tapatolu tapafā tatau ʻe ua. Ko ha meʻa tapafā ko ha meʻa loli makehe ʻoku tatau hono tafaʻaki ʻe fā, ʻo ʻuhinga ʻoku tatau fakatouʻosi foki hono ngaahi tapatefa.
Ko e Tuʻunga ʻa Pythagoras
Ko e makatuʻunga ʻo e lau ʻo e tapatefa ko e tuʻunga ʻa Pythagoras. ʻI he taimi ʻoku tafaʻaki ʻe ha tapatefa ha meʻa loli pe meʻa tapafā, ʻoku fakatupu ai ha tapatolu tapafā tatau ʻe ua. ʻI hono ngāueʻaki ʻo e tuʻunga ni, ʻe malava ke lau ʻa e tapatefa ʻaki hono ngāueʻaki ʻo e ngaahi loloa ʻo e ngaahi tafaʻaki. Ki he meʻa loli kotoa pē, ko e tapatefa ko e hypotenuse ʻo e ngaahi tapatolu ʻoku fakatupu.
Lau ʻo e Ngaahi Tapatefa: Ko e Ngaahi Meʻangāue ʻOku Ke Fiemaʻu
Ko e Kalakuleita Sivi Fakatapafā Pauʻu
ʻOku tuku atu ʻe he Kalakuleita Sivi Fakatapafā ʻa Chippy Tools ke ke ma’u faingofua ʻa e ngaahi tapatefa ʻo ha meʻa loli pe meʻa tapafā pē. Kamata ʻaki ʻa e hū ʻo e loloa mo e laulahi, pea tuku ʻa e kalakuleita ke fai ʻa e meʻa pauʻu!
Ko e Fomula
Ko e fomula ke lau ʻaki ʻa e tapatefa ʻo ha meʻa loli pe meʻa tapafā:
tapatefa = Aka Tapafā(loloa^2 + laulahi^2)
ʻOku ngāue ʻa e fomula ni ki ha fōtunga pē ʻoku hoko ai ʻa e tapatefa ko e hypotenuse.
Ngaahi Fakatātā Fakapoʻuli
Lau ʻo e Tapatefa ʻo ha Meʻa Tapafā
Kuo ke fifili, “Ko e hā e tapatefa ʻo ha meʻa tapafā 30x30?” Hū ngofua pē ʻa e loloa ʻo e tafaʻaki ki he kalakuleita. ʻI he muimui ki he fomula, ko e tapatefa:
tapatefa = Aka Tapafā(30^2 + 30^2) = Aka Tapafā(1800) ≈ 42.43
Ma’u ʻo e Loloa ʻo e Tapatefa ʻo ha Meʻa Loli
Ka kapau ʻoku ke fiemaʻu ke ʻilo ʻa e tapatefa ʻi ha ngaahi tafaʻaki kuo ʻomi? Fakakaukau ki ha meʻa loli ʻoku 40 hono loloa mo 20 hono laulahi. Fakahū ʻa e ngaahi fua ni ki he fomula:
tapatefa = Aka Tapafā(40^2 + 20^2) = Aka Tapafā(2000) ≈ 44.72
Tuku ʻa e Kalakuleita Sivi Fakatapafā ke fai maʻau ʻa e ngāue ni taʻe ha meʻa taha pē!
Ko e Hā ʻOku Ke Ngāueʻaki ai ʻa e Kalakuleita Tapatefa ʻa Chippy Tools?
Kuo fakatuʻutaʻa ʻa e Kalakuleita Sivi Fakatapafā ki he faingofua mo e fakatuʻutāmaki, ʻo lelei maʻa:
- Kau langa ʻoku nau fiemaʻu ha ngaahi fua tapatefa totonu ki he ngaahi polokalama.
- Kau fakatuʻutuʻu fakalotofale ʻoku nau fua ʻa e ngaahi palani fakalotofale pe ko e nofoʻanga ʻo e ngaahi meʻa loki.
- Kau ʻeiki ʻapi ʻoku nau fua ʻa e ngaahi loki ke sio ki he fe’unga ʻa e naʻinaʻi.
Pea toe, ʻoku fua ʻa e ngaahi lau ʻi he ngaahi ʻuta kehekehe, ʻo fakapapauʻi ʻa e totonu ʻi ha fakakaukau kotoa!
