Pyramid - scan. Skena mbhoshongo ukuze kunenze nisondelane. scan iphepha

Unxantathu, sikwele, calantsatfu, trapezoid nabanye - zeJiyomethri esigabeni i isayensi ngqo. Pyramid - a polyhedron. Ngesisekelo lesi sibalo a ipholigoni, icala langasezantsi libe ubhekene onxantathu kokuba vertex ezivamile, noma trapezoid. amamodeli bazwisise cwaningo kanye iyiphi into weJiyomethri. Basebenzisa impahla ezihlukahlukene kakhulu kusukela lapho ukhona iphiramidi. Ingaphezulu sibalo yehlukene kaningi okubalwa, efakwe kwi indiza, ngokuthi scan wakhe. Yakha indlela sakhiwo kuzokusiza zidlulisela izinto flat polyhedrons ngakuthathu selimazi geometry. Iskena iphepha noma amakhadibhodi akulula ukwenza. Ikhono okudingekayo ukwenza umdwebo osayizi isethi.

Izimpahla kanye nezinsiza

Modeling kanye nokuqaliswa ivolumu enezici ngamajamo weJiyomethri - inqubo ezithakazelisayo futhi kujabulise. Iphepha zingenziwa inani elikhulu izakhiwo ezahlukene. Ukuze usebenze uzodingwa:

• iphepha noma paperboard;
• sikelo;
• ipensela;
• umugqa;
• ikhampasi;
• iraba;
• glue.

Kuchazwa nemingcele

Okokuqala, uchaze ukuthi kuyoba mbhoshongo. Skena lesi sibalo ngesisekelo sokuthi kukhiqizwe umumo ngobuningi. Iya emsebenzini kuzodinga ngokunemba okuphelele. Ngesikhathi umdwebo okungalungile sibalo Jomethri ngeke ukuqoqa. Ake sithi ufuna ukwenza isakhiwo iphiramidi njalo esingunxantathu.

Noma yimuphi umzimba weJiyomethri anezakhi ezithile. Lesi sibalo base ipholigoni njalo, lobude baso afakwa ku phakathi nendawo. Njengoba base kuyakhethwa unxantathu equilateral. Leli lungiselelo icacisa igama. Uhlangothi imiphetho at mbhoshongo - unxantathu, ogama inombolo incike ekhethiwe polyhedron isizinda. Kulokhu, kuzoba ezintathu. Kubalulekile futhi ukwazi ukuthi wawungakanani zonke izingxenye, lapho mbhoshongo utawubhalwa. Iskena zamaphepha kwenziwe ngokuhambisana zonke weJiyomethri idatha ukuma. Amapharamitha imodeli esizayo esibekiwe kusengaphambili. Kulezi idatha, ukukhetha incike ezisetshenziswa.

Kungenzeka kanjani ukuthi ngibe scan iphiramidi njalo?

Ngesisekelo imodeli ephepheni noma amakhadibhodi. Umsebenzi iqala umdwebo mbhoshongo. Figure amelwe ifomu ukunwetshwa. Surface isithombe ephepheni oluhambisana Ubukhulu eyayikhethwe kusengaphambili futhi imingcele. mbhoshongo avamile has a base we ipholigoni njalo, futhi ukuphakama maqembu ngokusebenzisa isikhungo salo. Sikwenza imodeli esilula isiqalo. Kulokhu - kuba nombhoshongo ocijile esingunxantathu. Nquma usayizi ukuma olukhethiwe. Ukwakha imibhoshongo scan kabani base kuyinto unxantathu equilateral, maphakathi ishidi, ukusebenzisa irula lapho kusetshenzwa kanye ipeni, ukudweba inikezwe usayizi base. Eceleni ohlangothini ngalunye idwetshwa ngohlangothi ubuso mbhoshongo - onxantathu. Manje siya ukwakhiwa yabo. Ubukhulu ohlangothini ebusweni ezinhlangothini onxantathu yokulinganisa ikhampasi. Nomlenze ikhampasi isethwe ku phezulu base zaveza futhi wenze notch. Isenzo uphinda, ukuthuthela ephuzwini elilandelayo unxantathu. Empambana okubangelwa izenzo ezinjalo, ubuso ohlangothini ichaze vertices of iphiramidi. Zikuxhuma sizindza. Ukudweba ukuthola iphiramidi. Ukuze ukusondelana Umumo volumetric ezinhlangothini lateral ubuso unikeze valve. Dorisovyvat trapezoid encane.

inhlangano isakhiwo

Sika nge sikelo eyenziwe nentaba umdvwebo. Ngomusa goba scan zonke imigqa. Amaphayiphu abagqoke nge shape trapezoid ngaphakathi ukuze ubuso bayo ivaliwe. Kuthambisa glue. Ngemva kwemizuzu engu-amathathu, inhlaka seyomile. Ivolumu sibalo usulungile.

Scan quadrangular mbhoshongo

Okokuqala, cabanga ukuthi ifana sibalo Jomethri, layout okuzokwenziwa akhiwe. Base kuyakhethwa mbhoshongo quadrangle. izimbambo side - onxantathu. Ukuze usebenze usebenzisa izinto ezifanayo kanye namathuluzi, njengoba kule nguqulo odlule. Umdwebo kwenziwa iphepha ngepeniseli. Maphakathi ishidi ukudweba isikwele nge nemingcele akhethiwe.

Ngasinye ohlangothini ukuhlukana base ngesigamu. Dweba perpendicular, okuzoba ukuphakama ubuso esingunxantathu. Isixazululo ikhampasi obuphelele alinganayo ohlangothini ubuso mbhoshongo, ukwenza perpendiculars serifs, ukubeka isisekelo sayo umlenze phezulu. Kokubili engela kolunye uhlangothi base ukuxhuma iphuzu awuthola perpendicular. Umphumela phakathi ukudweba isikwele, ku bombo ngesineke onxantathu. Ukuze ulungise imodeli ku eziseceleni dorisovyvayut valve asizayo. Ukuze uthole okunokwethenjelwa ngokwanele yasibamba emapheshana isentimitha ububanzi. Pyramid ilungele inhlangano.

Isigaba sokugcina ukuqaliswa kusakhiwo

Okuholela usika izingcezu iphethini eduze nentaba. Lahlelwa ngoba imigqa agobe ephepheni. Collection ivolumu izibalo ezivezwa gluing. Amaphayiphu enikeziwe Athambisa glue silungise imodeli okuholela.

onobuhle volumetric bobunjwa eziyinkimbinkimbi

Ngemva kokwenza polyhedron onobuhle elula kungaba udlulele bobunjwa eziyinkimbinkimbi weJiyomethri. Scan mbhoshongo incishisiwe kunzima kakhulu ukubulawa. lezisekelo zawo ziyisikhumbuzo polyhedra efanayo. Uhlangothi ubhekene - a trapezoid. Kulandzelana kwalokucuketfwe lokuhleliwe umsebenzi kuyoba naleyo okwenza mbhoshongo elula. Scan kuyoba nzima kakhudlwana. Ukuze enze umdwebo usebenzisa ipensela, umbusi futhi ikhampasi.

Isakhiwo umdwebo

mbhoshongo Scan incishisiwe yenziwa ngezigaba eziningana. ubuso uhlangothi iphiramidi ufushanisiwe kuyinto trapezoid, lezisekelo - polyhedra ezinjalo. Ake sithi lesi sikwele. On ephepheni trapezoid enze drawing nge Ubukhulu esithile. Ezinhlangothini izibalo okuholela kuthiwa asinikeze nomgwaqo. Umphumela unxantathu isosceles. uhlangothi lwakhe ikhampasi wokulinganisa. Thatha iphe- lephepha, sakha umbuthano engaba okuyinto ibanga kulinganiswa.

Esigabeni esilandelayo - ukwakhiwa emaphethelweni lateral, okuyinto iphiramidi ufushanisiwe. Scan wenziwa ngaphakathi esiyingini uyalingana. Ukulinganisa ikhampasi base engezansi trapezoid. Siphawula ku kwesiyingi amaphuzu amahlanu ezixhunywe ne isikhungo line yayo. Sine onxantathu ezine equilateral. isilinganiso Compass we trapezoid idwetshwa uyibhala ahlukene. Le libanga ukuhlehlisa idwetshwa ohlangothini onxantathu ngamunye. Amaphuzu etholwe axhunyiwe. Ubuso ohlangothini trapezoid sekulungile. It kuphela uhlala ukudweba base engenhla nengezansi mbhoshongo. Kulokhu, la polyhedra - izikwele. I engenhla futhi base engezansi ngowokuqala trapezium dorisovyvat izikwele. Umdwebo libonisa zonke izingxenye elinendawo iphiramidi. Scan isicishe ilungele. It kuphela uhlala ukuqedela valve elihlangana ezinhlangothini isikwele kanye ezincane omunye ubuso trapezium.

Ukugcwaliswa ukumodeliswa

Ngaphambi gluing volumetric sibalo Ukugwala nentaba wasika nge sikelo. Ngokulandelayo, scan eligoqiwe ngokucophelela kanye imizila uyabhalwa. Ukubeka valve refueled ngaphakathi imodeli. amafutha abo glue yayicindezele emaphethelweni alo mbhoshongo ocijile. Amamodeli ukunikeza ezomile.

Ukukhiqizwa onobuhle ezahlukene polyhedra

Buciko onobuhle volumetric ngamajamo weJiyomethri - okuhlangenwe nakho okuthakazelisayo. Ukuze sizifunde size sizazi kahle, kufanele uqale nge ukuqaliswa kwe-amaskeni kakhulu elula. Kancane kancane usuka yezandla ezilula ngaphezulu onobuhle eziyinkimbinkimbi, ungakha imiklamo eyinkimbinkimbi kakhulu.
