Iphiramidi-ekwabizwa ngokuba yiPiramidi

Inkcazelo emfutshane:

Iphiramidi, ekwaziwa ngokuba yiphiramidi, luhlobo lwepolihedron enamacala amathathu, eyilwe ngokudibanisa amacandelo omgca othe ngqo ukusuka kwivertex yepolygon ukuya kwindawo engaphandle kwenqwelomoya apho ikhoyo.Ipolygon ibizwa ngokuba sisiseko sephiramidi . Ngokuxhomekeke kwimilo yendawo engezantsi, igama lephiramidi likwahluke, kuxhomekeke kwimilo yepolygonal yendawo engezantsi. Iphiramidi njl.

Ingcaciso yeMveliso

Isiseko sephiramidi:Ipolygon ekwiphiramidi ibizwa ngokuba sisiseko sephiramidi.
Amacala ephiramidi:Ubuso bephiramidi ngaphandle kwesiseko bubizwa ngokuba ngamacala ephiramidi. .
Icala lephiramidi:Umphetho oqhelekileyo wamacala ajongeneyo ubizwa ngokuba ngumphetho wecala wephiramidi.
Ukuphakama kwephiramidi:Incopho eqhelekileyo yamacala kwiphiramidi ibizwa ngokuba yincopho yephiramidi.
Ukuphakama kwephiramidi:Umgama ukusuka kwincopho yephiramidi ukuya kwisiseko ubizwa ngokuba bubude bephiramidi.
Ubuso obunqamlezileyo bephiramidi:Icandelo lephiramidi elidlula kwincam ezimbini zecala elingadibananga libizwa ngokuba bubuso obudiagonal.

Iimpawu

Iphiramidi luhlobo olubalulekileyo lwepolyhedron, ineempawu ezimbini ezibalulekileyo:
①Ubuso obunye buyipoligoni;
②Obunye ubuso ngoonxantathu abane-vertex eqhelekileyo, kwaye ezi zimbini ziyimfuneko.
Ngoko ke, ubuso obunye bephiramidi bunepolygonal, kwaye obunye ubuso bungunxantathu. Kodwa kwakhona qaphela ukuba "ubuso obunye yipolygon, kwaye bonke ubuso bungonxantathu" ijometri ayiyonto iphiramidi.

Ithiyori

Ithiyori: Ukuba iphiramidi inqunywe ngenqwelomoya ehambelana nesiseko, icandelo eliphumelayo lifana nesiseko, kwaye umlinganiselo wendawo yecandelo ukuya kwindawo yesiseko ulingana nomlinganiselo wesikwere womgama ukusuka kwisiseko. incam yecandelo ukuya kumphakamo wephiramidi.
I-Deduction 1: Ukuba iphiramidi inqunywe ngendiza ehambelana nesiseko, ngoko umgca wecala kunye nokuphakama kwephiramidi kwahlulwa kumlinganiselo ofanayo ngecandelo lomgca.
I-Deduction 2: Ukuba iphiramidi inqunywe ngendiza ehambelana nesiseko, umlinganiselo wendawo yecala lephiramidi encinci kwipiramidi yasekuqaleni nayo ilingana nomlinganiselo wesikwere sokuphakama kwawo okuhambelanayo, okanye umlinganiselo weendawo zabo ezisisiseko.
