Imigqa perpendicular futhi izakhiwo zabo

Perpendicularity ibizwa ngokuthi ubuhlobo phakathi kwezinto ezehlukene Euclidean isikhala - izindiza ngqo zithwala subspaces nokunye. Kulesi sihloko thina sihlolisise perpendicular imigqa izici isici ephathelene nalokho. Olayini ababili ingashiwo perpendicular (noma interperpendicular) uma wonke amagumbi amane, okuyinto akhiwa empambana zabo, akha ngokuqinile by degrees ayisishiyagalolunye.

Kukhona izakhiwo ezithile imigqa perpendicular ukusebenza indiza:

• I ezincane engele ukuthi akhiwa empambana imigqa emibili endizeni, ngokuthi igebe eliphakathi imigqa emibili ngqo. Kuleli qophelo akayi phezu perpendicular.
• Ngokusebenzisa iphuzu okuyinto ingeyona umugqa esithile, ungase ubambelele umugqa owodwa kuphela, okuyinto perpendicular umugqa inikezwe.
• I kwesibalo umugqa perpendicular indiza, kusho ukuthi umugqa kuyoba perpendicular yonke imigqa esuke kule indiza.
• Rays noma izingxenye olele imigqa perpendicular nayo izofakwa ukubizwa ngokuthi perpendicular.
• Perpendicular ngqo ethize uyakuthiwa ingxenye umugqa okuyinto perpendicular futhi has njengoba omunye emikhawulweni yaso kwaze kwaba seqophelweni lokuba ephambana emgqeni futhi Imi.
• Ukusuka kunoma iliphi iphuzu okungahambisani abalale umugqa unikezwa, kungenzeka futhi bekungamelwe niziyeke emgceni locondzile eyodwa kuphela, perpendicular ke.
• Ubude emgceni locondzile perpendicular kwehla kusuka iphuzu ngakolunye umugqa izobizwa ibanga ukusuka ngqo iphuzu.
• Isimo lemigqa perpendicular wukuthi labo kungenziwa ngokuthi ngqo, okuyinto aphambana ngokuqinile at engele kwesokudla.
• Ibanga ukusuka iphuzu elithile ka omunye parallel ngqo kuya yesibili emgceni locondzile izobizwa ibanga phakathi imigqa emibili ngokulinganisa.

Ukwakha imigqa perpendicular

imigqa perpendicular esakhiwe ebhanoyini ngosizo-polygon. Noma yimuphi draftsman kumele kukhunjulwe ukuthi isici esibalulekile saleso ipholigoni ngamunye ukuthi njalo has a engela kwesokudla. Ukwakha imizila emibili perpendicular, kudingeka ukuhlanganisa omunye sezinhlangothini zombili ze-engela ilungelo lethu Ukudweba ipholigoni enentambo enikeziwe ukuchitha iqonde wesibili ohlangothini yesibili ye-engeli kwesokudla. Ngakho-ke izokwakhiwa imigqa emibili perpendicular.

isikhala ezintathu-ntathu

Kuvele Eqinisweni ezithakazelisayo wukuthi emigqeni perpendicular ezingase zithathwe e izikhala ezintathu-ntathu. Kulokhu, la izobizwa imigqa emibili eqondile, uma okufanayo, ngokulandelana, noma yiziphi ezinye imigqa emibili ungephansi kwemandla indiza efanayo futhi perpendicular ke. Ngaphezu kwalokho, uma indiza perpendicular kungaba imigqa emibili kuphela isikhala ezintathu-ntathu - ezintathu. Ngaphezu kwalokho, e izikhala multidimensional inani lemigqa perpendicular (noma izindiza) kungenziwa olunye anda.
