Iphiramidi-Futhi Yaziwa NjengePiramidi Efakiwe Isithombe

Iphiramidi - Eyaziwa nangokuthi Iphiramidi

Incazelo emfushane:

Iphiramidi, eyaziwa nangokuthi iphiramidi, iwuhlobo lwe-polyhedron enezinhlangothi ezintathu, eyakhiwe ngokuxhuma izingxenye zemigqa eqondile ukusuka ku-vertex ngayinye yepholigoni ukuya endaweni engaphandle kwendiza lapho itholakala khona.Ipholigoni ibizwa ngokuthi isisekelo sephiramidi . Kuye ngokuma kwendawo engaphansi, igama lephiramidi libuye lihluke, kuye ngokuthi i-polygonal shape yendawo engezansi. Iphiramidi njll.

Incazelo Yomkhiqizo

Isisekelo sephiramidi:Ipholigoni ephiramidi ibizwa ngokuthi isisekelo sephiramidi.
Izinhlangothi zephiramidi:Ubuso bephiramidi ngaphandle kwesisekelo bubizwa ngokuthi izinhlangothi zephiramidi. .
Imiphetho eseceleni yephiramidi:Unqenqema oluvamile lwezinhlangothi ezincikene lubizwa ngokuthi unqenqema oluseceleni lwephiramidi.
I-apex yephiramidi:I-apex evamile yezinhlangothi ephiramidi ibizwa ngokuthi i-apex yephiramidi.
Ukuphakama kwephiramidi:Ibanga ukusuka esiqongweni sephiramidi kuya esisekelweni libizwa ngokuthi ukuphakama kwephiramidi.
Ubuso obuyi-diagonal bephiramidi:Ingxenye yephiramidi edlula emaphethelweni amabili angasondelene ibizwa ngokuthi ubuso obuyi-diagonal.

Izici

Iphiramidi iwuhlobo olubalulekile lwe-polyhedron, lunezici ezimbili ezibalulekile:
①Ubuso obubodwa buyipholigoni;
②Obunye ubuso bungonxantathu abane-vertex evamile, futhi kokubili kudingekile.
Ngakho-ke, ubuso obunye bephiramidi bu-polygonal, kanti obunye ubuso buyinxantathu. Kodwa futhi phawula ukuthi "ubuso obubodwa buyipholigoni, futhi bonke ubuso bungonxantathu" ijometri ayiyona iphiramidi.

Ithiyori

I-Theorem: Uma ipiramidi isikwa ngendiza ehambisana nesisekelo, isigaba esiwumphumela sifana nesisekelo, futhi isilinganiso sendawo yesigaba nendawo yesisekelo silingana nesilinganiso sesikwele sebanga ukusuka phezulu kwesigaba kuya ekuphakameni kwephiramidi.
I-Deduction 1: Uma ipiramidi isikwa yindiza ehambisana nesisekelo, khona-ke unqenqema oluseceleni nokuphakama kwephiramidi kuhlukaniswa ngesilinganiso esifanayo ngesigaba somugqa.
I-Deduction 2: Uma ipiramidi isikwa ngendiza ehambisana nesisekelo, isilinganiso sendawo eseceleni yephiramidi encane kuya kwiphiramidi yasekuqaleni nayo ilingana nesilinganiso sesikwele sokuphakama okuhambisanayo, noma isilinganiso sezindawo zabo eziyisisekelo.
