Origami: Indlela yokwenza dodecahedron ezenziwe iphepha

Dodecahedron - a polyhedron ehlanganisa 12 pentagons ezifanayo. Lesi sibalo ngoba lo msebenzi base isethi kusukela amakhalenda ideskithophu ukuze openwork amathoshi okwesikhashana.

Indlela yokwenza dodecahedron ezenziwe iphepha?

Ungakwazi ukwakha ngokwakho pentagon - ilula futhi iqinisekisa okusezingeni eliphezulu ngokunemba umdvwebo. Ukuze kwakhiwe pentagon njalo kuzodingeka ikhampasi nombusi wezwe. Dweba indilinga usayizi oyifunayo. Chitha kuphi engaba. Ukwenza olunye perpendicularly nalokho engaba. Khona kwasuka omunye wabayishumi radii ihlukaniswe yaba izingxenye ezimbili alinganayo. uhhafu ngamunye kuyoba engaba ezahlukene, indilinga lencane, okuyinto bazocula indima asizayo. Okulandelayo, xhuma maphakathi umbuthano asizayo endaweni lapho eziyisisekelo umbuthano engaba ephambana nezinye (isibonelo, iphoyinti A). Umugqa okuholela ngeke aphambana emjikelezweni asizayo ngaso iphuzu elithile - B. Ibanga AB ingenye-lweshumi mbuthano. Lokho ibanga ikhampasi ukumaka phezu circle isizinda, bese uxhuma la maphuzu asebenza ngayo imigqa uqonde eyodwa - a pentagon njalo ulungile!

Kukhona nezinye izindlela. Ngokwesibonelo, i-pentagon kwakhiwe usebenzisa protractor, kodwa akuqinisekisi ukunemba kwalo. Iningi indlela eLehi - ukuthatha isikimu ngomumo eyenziwe, ukuphrinta, futhi lokhu, "iphethini" isivele Siwohloza kwelungelo iphepha yezandla. Kodwa le ndlela, nakuba elula, akuyona njalo ofanele - ngoba ngezinye izikhathi udinga ukwenza dodecahedron of usayizi ethile. Ungakwazi khulisa a pentagon olulodwa usayizi oyifunayo futhi uzitholele kuye kuphela, bese ukwakha sibalo ku mdwebo ongezansi.

Kodwa "isibonelo" - akakabi ukulungele Hack. Indlela yokwenza dodecahedron ezenziwe iphepha? Lokhu kuzodinga:

1. Iphepha ukuminyana efanelekayo. Akufanele kube too mncane noma obukhulu kakhulu - okungcono 220 g / m², it has a paperboard kwabantu, okuyinto edayiswa amasethi izingane. Nakuba leyakhiwe ngemabhokisi obukhulu kungenzeka ukudala izibalo ngakuthathu, udinga kuphela ukufaka ama-inqubo yonke emphethweni - snick noma push ezinhle, ukuthi baphumula kahle futhi ngokulinganayo insaliwe.

2. sikelo, ipensela, iglu, inaliti ukunitha noma zokubhala ummese

Amathiphu kokwenza dodecahedron

Iphepha at nesibaya kuyinto efiselekayo kancane push inaliti, ohlangothini blunt we zokubhala ummese noma okuthize abukhali kodwa hhayi ukusika. emphethweni Neat flat - isigamu impumelelo.

Uma inhlaka akukhona uhlangothi, dodecahedron ingalandwa, njengoba umakhi, ungavula imbobo kanye crease bese umane ufaka ingxenye ku komunye nomunye.

Uma ukuqoqa dodecahedron e amasu Modular (imiyalelo ngezansi), bese emalungeni prokleivat ezifiselekayo noma ukudla ukulungisa, kusukela isakhiwo kuba esitebeleni kuphela ngemva kokulilungisa module zokugcina.

Dodecahedron e origami amasu

Module Origami - isisekelo esihle kakhulu le dodecahedron. Indlela yokwenza dodecahedron ephepheni e inqubo Modular? 30 bazodinga aboncamane nofana amashidi sikwele ephepheni. Ngamunye amapheshana agobe, bese ingxenye ngayinye ukuze agobe kolunye uhlangothi - kuzokwenza "inkositini" e anezele ezine. Ngezinye izikhathi, uma ishidi akusona isikwele, yenza "harmonica" e amathathu kwalokho. Ngenxa yalokho onakho ngezandla strip emincane promougolnaya. Khona-ke, ohlangothini isikwele eceleni emincane endaweni nokugoba ngamunye. Emakhoneni akhiwa kwelinye direction - ikusasa yasibamba ukuba refueled ku "harmonica". Khona-ke bend module owangaphakathi Slant ngokuphambeneyo kusukela amakhona ohlangothini elincane. Ngakho, enye module origami dodecahedron - a ngakuthathu, sifaka ebukhali izinsiko zombili futhi amakhona sibalo esizayo. Lapho bonke amamojuli zilungele, ungaqala inhlangano.

Umhlangano iqala nge-node olulodwa ofuna ukuthatha amamojuli ezintathu. Isibalo ngezansi esiluhlaza, pink yellow origami ins. imidvwebo inhlangano kahle elula, futhi lezo zibalo kalula ukuphatha ngisho imfundamakhwela.

Yini yezandla zingenziwa ngesisekelo a dodecahedron?

Ngasinye ohlangothini dodecahedron ezenziwe iphepha - a pentagon flat, zona ngokwazo kungaba isisekelo ezihlukahlukene kanye namafomu yinqaba. Ngokwesibonelo, e-isithombe ngezansi pentagon indawo inkanyezi ezinhlanu olucijile. Izimbambo kule sibalo azitholakali, nakuba kucatshangwa. Indlela yokwenza dodecahedron ezenziwe iphepha esime inkanyezi? Miselela yilokho kukhukhula, eboniswe ngenhla, ngamunye pentagon edingekayo sibalo ezinhlanu enamaphoyinti bese uxhuma nabo hhayi izimbambo futhi eziqongweni.

Kulesi sithombe uvezwa dodecahedron stellated. Ngesikhathi enhliziyweni yomuntu ngamunye "uvumelanise" kusese pentagon efanayo.

kungenzeka kwakhiwa noma iyiphi ukuma volumetric esikhundleni amaphiramidi pentagonal.

Esikhathini isithombe ngezansi njengoba pentagons enze origami izifunda ezengeziwe eziyinkimbinkimbi, okuyinto unesithakazelo leli su kungatholakala ezincwadini.

Kunoma ikuphi, ukuthuthukiswa ngisho elula inhlangano isikimu dodecahedron kakade ukunikeza amathuba omkhulu wobuciko futhi uthole ongakhetha abo.
