Origami: Indlela yokwenza dodecahedron ezenziwe ngephepha

Dodecahedron - emacala equka wepentagons ezifanayo 12. Eli nani ngenxa yobugcisa isiseko obubekwa iikhalenda desktop ukuya openwork iithotshi emsebenzini.

Indlela yokwenza dodecahedron ezenziwe ngephepha?

Uyakwazi uzakha a pentagon - kulula kwaye iqinisekisa ngqo zokuzoba eliphezulu. Ukuze ukwakha pentagon rhoqo kuya kufuneka ikhampasi kunye nomlawuli. Zoba isangqa kubungakanani efunekayo. Chitha naphi radius. Ukuze enze omnye perpendicularly kuso mgama. Emva koko enye radii yahlulwe kubini ngokulinganayo. isiqingatha nganye iya kuba radius ezahlukeneyo, isangqa encinane, neya kuthi yenze indima i nkarhinyana. Okulandelayo, qhagamshela embindini wesangqa abangabancedani ukuya kwindawo apho radius esisiseko isangqa inqumla elinye (umzekelo, ngaxa A). Umgca sisiphumo phambana isangqa abangabancedani kwindawo ethile - B. Umgama AB yi-yeshumi elinye kwisangqa. Oko ngumgama ikhampasi ukumakisha kwi isangqa kwesiseko, uze ukudibanisa ezi ngongoma xa imigca ethe ngqo omnye - i pentagon rhoqo ukulungele!

Kukho ezinye iindlela. Ngokomzekelo, omnye pentagon unako kwakhiwa kusetyenziswa neprotrektha, kodwa akuqinisekisi ukuchaneka kwayo. Eyona ndlela Lihayi - ukuthatha scheme esele zenziwe, uprinte, yaye ngenxa yoku, "ipateni" sele tinkering ye kubugcisa iphepha ekunene. Kodwa le ndlela, nangona elula, akusoloko efanelekileyo - ngenxa yokuba ngamanye amaxesha kufuneka wenze dodecahedron elimlinganiselo ethile. Unga yenza nkulu enye pentagon kubungakanani olifunayo uze uprinte yena yedwa, ngoko ukwakha umzobo kwi mzobo ungezantsi.

Kodwa "ipateni" - ayikho kodwa ukulungele zizame. Indlela yokwenza dodecahedron ezenziwe ngephepha? Oku kuya kufuna:

1. IPhepha loxinano efanelekileyo. Kufuneka ube mncane kakhulu okanye obukhulu kakhulu - ekukhethwa-220 g / m², ukuba abe paperboard ukuxinana, apho kuthengiswa iiseti abantwana. Nangona ezenziwe ikhadibhodi enkulu kakhulu kunokwenzeka ukwenza amanani-ntathu, kufuneka kuphela pre inkqubo-zonke Imihlubulo - snick okanye atyhale elungileyo, ukuba kakuhle ngokulinganayo egobile.

2. isikere, ipensile, iglu, ngenaliti anganithi okanye zokubhala imela

Iingcebiso kwi kokwenza dodecahedron

Iphepha le ivalile enqwenelekayo ukutyhalela kancinane inaliti, icala Ukuhl zokubhala imela okanye into ebukhali kodwa ngokusika. ezibayeni Ukucoceka flat - isiqingatha impumelelo.

Ukuba sikwi ayikho ngesandla, lo dodecahedron unako kuqokelelwa, njengoko umakhi, yenza imbobo ecaleni umsipha uze uyifake nje inxalenye zibe omnye komnye.

Ukuba ekuqokeleleni dodecahedron kwi indlela seemodyuli (imiyalelo ngezantsi), ngoko ke amalungu prokleivat enqwenelekayo okanye ezityiwa ukulungisa, ekubeni isakhiwo uba sizinzile kuphela emva ukulungisa umnqongo lokugqibela.

Dodecahedron in origami ubuchule

Module origami - isiseko esihle ngenxa dodecahedron. Indlela yokwenza dodecahedron ukusuka namaphepha njengobuchule yemodyuli? 30 Kuya kufuneka uxande okanye amaxwebhu isikwere ephepheni. Ngalinye amaphetshana agobe, ngoko isiqingatha ngasinye Wayitsala kwelinye icala - it "ikhodiyani" kwi nezongezelelo ezine. Ngamanye amaxesha, ukuba iphepha ayikho isikwere, yenza "harmonica" ezintathu zokudibanisa. Ngenxa yoko onayo kwizandla zinomtya nemxinwa promougolnaya. Emva koko, kwicala ngalinye xande ecaleni emxinwa yendawo Rise. Corners akhiwa kwicala elinye - ikamva ngesibopheleli ukuba refueled kwi "harmonica". Emva koko Wayitsala umnqongo ngaphakathi sivune kwikonw ngekona kwiikona kwicala encinane. Ngenxa yoko, omnye imodyuli origami dodecahedron - i-ntathu, oko kuquka elintlangothi mbini kunye neekona ngemfano elizayo. Xa ulungele yonke iminqongo, ungaqala ibandla.

Indibano iqala udumbo eyodwa apho ufuna ukuthatha iimodyuli ezintathu. Lo mzobo ungezantsi kukho oluhlaza, opinki kunye yellow ins origami. Assembly imizobo ngendlela elula, yaye loo manani ingaphatha ngokulula nkqu lo mfundi.

Ziziphi yezandla zingenziwa kwi Ngokwesiseko dodecahedron?

kwicala ngalinye dodecahedron ezenziwe ngephepha - a pentagon tyaba, nto leyo ngokwayo nga kuba sisiseko ezahlukeneyo kunye neefom engaqhelekanga. Umzekelo, kwi ifoto ngezantsi pentagon endaweni inkwenkwezi-kwakubonisa ezintlanu. Iimbambo kulo mzobo abafumaneki, nangona Kucingelwa. Indlela yokwenza dodecahedron ezenziwe ngephepha xa elimile inkwenkwezi? Esikhundleni xa kutshayelwa, eboniswe ngasentla, pentagon nganye efunekayo isafobe-etsolo ezintlanu senginginya nodibaniso kuzo hayi iimbambo obuphezu.

Kule ifoto inikwa dodecahedron stellated. Xa intliziyo "umqadi" nganye isekhona yewotshi yamasiba efanayo.

nayiphi imilo ngokomthamo ukuze kuyilwa endaweni iiphiramidi pentagonal.

Kwifoto ngezantsi njengoko kwipentagons enze iisekethe origami entsonkothileyo kakhulu, nto leyo banomdla kule ndlela inokufumaneka kule ncwadi.

Kuyo nayiphi na imeko, uphuhliso nkqu elula scheme ibandla dodecahedron sele ukunika amathuba ezinkulu bobuchule ukufumana iinketho zabo.
