Geometry okuchazayo - okungukuthi indiza okuqondile?

Ukuze uthole umbono wokuthi ngendaba wasebenzisa umfanekiso wakhe ephepheni noma esibukweni. Ngokuvamile, isihloko isithombe nanoma yimuphi omunye amaqembu akukuniki isithombe esiphelele injalo-ke, kuyadingeka ukwamukela kwelivi yayo ezindizeni ezimbili noma ezintathu. Ngukwejwayeza inqubo lelivakalako, indiza lapho projection senzeka, perpendicularly komunye nomunye. Cabanga, yiziphi izinhlobo ezahlukene izindiza. Njengamanje bobathathu, futhi akha isikhala esingunxantathu ngendlela engela kwesokudla.

Ngamunye izindiza kwelivi unegama ayo futhi lettering. indiza Frontal - a thwi ibekwe phambi kwethu indiza amehlo lelivakalako. Ngokucaca - kungcono indiza, lapho sibhekene, ukuthi, esiwuhlolayo indiza ye isithombe ... Designated phambili indiza ye-Latin incwadi V

indiza ovundlile kuyinto perpendicular phambi. Ngomqondo ongokomfanekiso, indiza ovundlile - lena indiza ukuthi amanga nathi "ngaphansi kwezinyawo zakhe." Ivame okhonjiswe H. incwadi

I wesithathu main kwelivi izindiza ibizwa ngokuthi iphrofayela. Njengoba indiza frontal, itholakala thwi futhi yakha engela ezilungile odlule ezimbili. Bheka indiza iphrofayela Latin incwadi W.

Lapho empambana pairwise izindiza ezintathu idatha elakhiwe Ukudidiyela-eksisi x, y, z. Lokhu Okusizayo imisebe perpendicular nge vertex ezivamile ezimpambanweni zomgwaqo izindiza ezintathu lelivakalako, okhonjiswe incwadi O.

Ukuze uthole isithombe enemininingwane into, kuyadingeka ukuhlanganisa izithombe atholakala e-ubuso obuthathu Okusizayo perpendicular. Kuze kube yimanje, i-obubili ye-engeli akusebenzise okuhlangana ngayo eyesithathu. indiza Frontal uhlala endaweni, ovundlile ijikelezwe phansi ngu-90 ° kanye x-axis, indiza iphrofayela ijikeleziswa kwesokudla 90 ° endleleni z axis. Ngakho ezimbili zokugcina indiza ahambisana phambi (elise ngezansi ovundlile, iphrofayli - ngakwesokudla).

I-geometry achazayo iyiphi ezinqumela ise indiza umdwebo kungachazwa ngezindlela ezahlukene: projection ezintathu ungahlali emgceni locondzile amaphuzu, umugqa kwelivi iqonde futhi iphuzu ngaphandle-ke, kanye emisebenzi parallel noma imigqa intersecting noma isibalo indiza.

Ngemva kwendiza eyinhloko kwelivi obuka indiza kungathatha iinjamiso ezilandelako:

1. Kungaba non-perpendicular phi of them. Khona-ke -. Ngakho-okuthiwa. indiza ejwayelekile.

2. Kungenzeka omunye izindiza ezintathu perpendicular ka lelivakalako. Esimweni esinjalo ubizwa ngokuthi nendawo projecting, profiled noma-projecting frontally-projecting, ngokulandelana, indiza okuyinto perpendicular ke.

3. indiza ingase perpendicular ababili kwathi parallel lwesithathu. Khona-ke kubizwa ngokuthi ngaphambili, ovundlile noma iphrofayela ngokulandelana.

Direct kungase kungene izikhundla ezilandelayo maqondana indiza:

1. anabo.

2. Kungaba zifana.

3. ephambana indiza (icala ekhethekile - njengoba perpendicular)

Esikhathini indiza kukhona imigca, ngokuthi nentaba futhi Frontale. It imigqa elele indiza kanye parallel izindiza ehlukene projection.

Noma yimuphi indiza kungenziwa imelelwa r. N. indiza trace, okungukuthi, imigqa kanye ngalo ephambana endizeni lelivakalako. Iminonjana indiza zibizwa futhi ngokuthi ovundlile, engaphelele kanye iphrofayli. Amaphuzu ezimpambanweni zomgwaqo indiza ye-eksisi projection kwi-eksisi kokuba iphuzu empambana mutual indiza ye ukulandelelwa, iminonjana ngokuvamile ngokuthi amaphuzu Vanishing indiza.

Ovundlile futhi frontal indiza iminonjana e izindiza we projection uqondane projection kwabo igama elifanayo. Kufanele kushiwo ukuthi bonke eyodwa evundla kabili indiza efanayo Okusizayo kuqondane and parallel ithrekhi ovundlile, kanye noma imaphi frontal layo Okusizayo kuqondane and parallel front end umzila walo.
