Flexagon Hack. Indlela yokwenza yezandla ngakuthathu?

Izihloko ezenziwe iphepha - kuyinto umhlaba wonke kwehlukahlukana zokudala. izingcezu Abaningi iphepha kusungulwe zezibalo. Ngokwesibonelo, eyaziwa emhlabeni wonke Hack flexagon futhi yasungulwa wezibalo isitshudeni sase-Princeton University Arturom Stounom ngo-1939. I flexagon bezijabulisa? Indlela yokwenza ezihlukahlukene flexagon futhi sijabulise izingane?

A yezandla fun aphume iphepha

Ngokusobala igama elithi Latin (flectere), kwakheka isisekelo igama, ke uzimisele noma eligoqiwe. Ngakho-ke flexagon - a ipholigoni, okungase okudalwe strip evamile lephepha elimhlophe. Isikhathi ngasinye, eguqa ipholigoni, sithola indiza entsha.

Flexagon ukuthi kunjani? Indlela yokukwenza kwesokudla lesi sibalo? Ngokuvamile wenze flexagon olunezinhlangothi flat, njengoba iyona elula. Ukusebenzisa ezihlukahlukene amaphethini kulezi izindiza, singajabulisa izingane of yezandla engavamile, futhi awubandakanye ukudalwa kokubili Planar nevolumu izibalo futhi ewusizo.

Flexagon: indlela yokwenza iphepha?

Kuphi ukuqala? Ngakho, sanquma ukwakha flexagon. Indlela yokwenza Hack esheshayo? Polygon uyahamba ngokushesha futhi kalula kusuka ishidi elilodwa iphepha noma, kodwa kungcono ukuba ukhethe esithambile futhi. Flexagon quadrangular ngokuthi tetrafleksagonami. Isibalo kokuba esime a iheksagoni, ngokuthi geksafleksagonom. ebusweni ngamunye has 6-imikhakha yayo onxantathu. Usekhona oktafleksagony (8 izinhlangothi) kanye dodekafleksagony (10 izinhlangothi). kanjani flexagon ngephepha? Isikimu zahlukahlukene kakhulu. Cabanga elula kakhulu, okuyinto kwenziwa geksafleksagon abavamile. Leli cebo elisetshenziswe kaningi.

Kulula ukudweba bebodwa, ngoba siqukethe kuphela iqembu onxantathu kwesokudla. Kodwa ungasebenzisa yesikumu elihlotshisiwe lapho okokuqala kulula babuthane yezandla. Uma wesifunda inqanyulwa, eligoqiwe ngesigamu futhi embondelene leaf izigaba, eguqa unxantathu ngamunye eziyingxenye indiza ehlukene. Lapho flexagon libuthene ngokugcwele, ukunamathisela kufike emniningwaneni wokugcina.

Isikhathi ngasinye kwezintathu evele ezine kuyodingeka umdwebo wakho. Ngemva kokufunda leli qhinga, khona-ke ungakwazi ukuya emsebenzini ngenhloso nangobuchule. Ephepheni ethafeni ukudweba unxantathu efanayo. Khona-ke inani imikhakha akha indiza. Triangles, ngokulandela imiyalelo, udinga goba, ukwakha ipholigoni oyifunayo. Kodwa wonke umuntu ekhetha indlela yabo, njengoba kuwusizo kakhudlwana phinda. Ngokufanayo, leli qhinga kwenzekani yimuphi ipholigoni-flexagon. Okuningi izikimu eziyinkimbinkimbi lezinombolo kancane kancane kangcono.

Iposikhadi-flexagon

Mathematical imodeli-flexagon ingane ngokuqinisekile ube nesithakazelo. Lena impahla okumangazayo iphepha singasetshenziswa diversely. Uma uyikha phezulu le izingcezu siphelile zibonisa izinhlamvu opopayi zezingane futhi inikeza ubufakazi ingane ubuhlakani ukuthi onobuhle zezibalo engase abe nesithakazelo.

Futhi ungakwazi beveza i iposikhadi omuhle kakhulu futhi engavamile, futhi akusiwona ihlaya. Indlela yokwenza ikhadi-flexagon? Uma usondela Laphezu lawa magama ukubingelela ngomntwana futhi imihlobiso Christmas, kuyoba isipho esikhulu uNcibijane. Kodwa uma uke izibalo ezimbi etholwe, ukuthola enye indlela yokuphuma. Ungakwazi umane ukuphuma isithombe sakho ozithandayo futhi waqhekeka waba onxantathu lalinganako, khona-ke kuyomelwe ethe njo ngokucophelela zonke izingxenye yezandla

imikhiqizo Bulk - ezihlukahlukene ngokuvumelana

Kukhona izibalo ngakuthathu. kanjani flexagon ivolumu ngephepha? Ukuze wenze lokhu, thatha isibonelo isikimu siphelile, esakhiwa 10 onxantathu equilateral ukukhonza imikhakha. Lesi sibalo ngokuthi trigeksafleksagon - okungukuthi, omningi walo iheksagoni kuyoba evele ezintathu. Yiqiniso, lena akuyona umkhawulo. Imodeli ingaqukatha 4, 5, kanye evele, futhi 10. Lezi flexagon zikhanga ngisho nakakhulu, noma esekelwe umqondo ofanayo. Kodwa ukuqoqa leso simangaliso kunjalo elula cha. Umthetho main lapho umfuziselo - ulandela imiyalelo. geksafleksagona Scheme 4 evele izobukeka kanje:

Nasi isibonelo esiya edangalisayo nakakhulu sibalo - nonageksafleksagon. Okungukuthi, abangabantwana flexagon ivolumu nge engele eziyisithupha, kanye evele kakade 9. Lokhu ithoyizi isivele abadala, ingane imodeli ezifana bunganehluli, kunoma yiliphi icala, ngaphandle kosizo kwabazali.

Ukuze uqonde butholakala enqubweni eyinkimbinkimbi yokuthela isikimu ukuthi ivolumu izibalo kuzothatha isikhathi. I preform kungcono ukuhlobisa nge imibala ehlukene ukugwema ukudideka phakathi kwenhlangano. Zama!
