Nkhani anapanga pepala - ndi dziko lonse zosiyanasiyana kulenga. yambiri pepala anausankha masamu. Mwachitsanzo, odziwika padziko lonse kuthyolako flexagon komanso anatulukira masamu wophunzira pa Princeton University Arturom Stounom mu 1939. Kuganizira flexagon? Kodi kupanga zosiyanasiyana flexagon ndi kukondweretsa ana?

A zamanja akangomutonza pepala

Nkosafuna Latin mawu (flectere), anapanga m'dzina, izo akufunitsitsa kapena apangidwe. Choncho flexagon - polygon, amene akhoza kuchita kulengedwa kuchokera Mzere mwachizolowezi pepala woyera. Nthawi iliyonse, kupinda polygon, ife tikupeza ndege yatsopano.

Flexagon zimene ziri ngati? Kodi kuchita izo bwino chithunzi ichi? Kawirikawiri kupanga hexagonal lathyathyathya flexagon, monga yophweka. Ntchito zosiyanasiyana dongosolo la ndege izi, ife tikhoza kusangalatsa ana a ntchito zamanja zachilendo, muwone iwo polenga onse planar ndi zithunzi buku komanso zothandiza.

Flexagon: bwanji kuti pepala?

Pati? Choncho, tinaganiza kuti alenge flexagon. Kodi kupanga kuthyolako mwamsanga? Polygon ati mwamsanga ndipo mosavuta ku pepala limodzi la mapepala mwina, koma m'pofunika osati kusankha zofewa kwambiri. Flexagon quadrangular otchedwa tetrafleksagonami. chithunzi A ndi mawonekedwe a hexagon, wotchedwa geksafleksagonom. Aliyense padziko amakhazikitsa 6-Boma Triangles. Komabe pali oktafleksagony (8 mbali) ndi dodekafleksagony (10 mbali). Kodi flexagon pepala? Chiwembu ndi yosiyanasiyana. Taonani lophweka, chimene ndi geksafleksagon wamba. chiwembu Izi ntchito nthawi zambiri.

N'zosavuta kudzatunga paokha, chifukwa imakhala yokha gulu la Triangles bwino. Koma mukhoza kugwiritsa ntchito chiwembu ornamented limene kwa nthawi yoyamba n'kosavuta kusonkhanitsa zamanja. Kamodzi dera la Kadulidwa, apangidwe mu theka ndi zakhala zikuzunza m'miyoyo magawo tsamba, aŵelama lililonse makona kupanga gawo la ndege osiyana. Pamene flexagon ndi anasonkhana kwathunthu, kumata tsatanetsatane lomaliza.

Pa aliyense wa pamalo anayi ndi zojambula zanu. Ataphunzira zolinga zawo, ndiye inu mukhoza kupita kuntchito akumvera. Pa pepala kumveka akokere makona chomwecho. Ndiye chiwerengero cha Boma zomwe ndi ndege. Triangles, malinga ndi malangizo, muyenera weramitsani, kupanga polygon ankafuna. Koma aliyense amasankha njira zawo, monga yabwino kwa pindani. Mofananamo, zolinga izi aliyense polygon-flexagon. Kwambiricho machenjerero a kanjedza bwino kukhala pang'onopang'ono.

Kalata-flexagon

Masamu chitsanzo-flexagon mwana adzakhala ndi chidwi. Ichi ndi katundu chodabwitsa pepala ingagwiritsidwe diversely. Pamwamba pa ndalama yomalizidwa akamachita mawonekedwe a zojambula ana ndi wapereka mwana namatetule umboni kuti zitsanzo masamu akhale chidwi.

Ndipo inu mukhoza anabwera ndi kalata kwambiri ndi zachilendo, ndipo si nthabwala. Kodi khadi-flexagon? Mukayandikira pa kali mawu moni kwa mwana ndi Khirisimasi zokongoletsa, zidzakhala mphatso yaikulu kwa chaka chatsopano. Koma ngati inu kanjedza zoipa analandira kupeza njira ina kunja. Inu akhoza kungoyankha kudula thunzi mumaikonda kugawanika mu Triangles ofanana, kenako ndi mosamala glued pa lililonse gawo la ntchito zamanja

Chochuluka mankhwala - zosiyanasiyana mogwirizana

Pali kanjedza atatu azithunzi omwe tikunena. Kodi flexagon buku la pepala? Kuti tichite zimenezi, kutenga Mwachitsanzo yomalizidwa chiwembu, chomwe 10 equilateral Triangles kutumikira m'magulu. chiwerengerochi amatchedwa trigeksafleksagon - kutanthauza chochuluka hexagon adzakhala pamalo atatu. Ndithudi, izi si malire. Lachitsanzo anyamula 4, 5, ndi pamalo, ndi 10. Izi flexagon ngakhale kokondweretsa kwambiri, ngakhale zochokera lingaliro lomwelo. Koma kusonkhanitsa chozizwitsa si mophweka. Ulamuliro waukulu pamene akumanga chitsanzo - malangizo. geksafleksagona chiwembu 4 pamalo lidzaonekera izi:

Pano pali chitsanzo cha zomwe zikuchitika kwambiri mantha chithunzi - nonageksafleksagon. Ndiko kuti, buku flexagon ndi kumathandiza kupeza ngodya zabwino zisanu ndi chimodzi, ndipo kali ndi kale 9. chidole Izi kale akulu, ndi mwana chitsanzo usakugwereni, Mulimonsemo, popanda thandizo la makolo.

Kumvetsa intricacies wa chiwembu kuti buku ziwerengero kudzatenga nthawi. The preform bwino kukongoletsa ndi mitundu yosiyanasiyana kuti asasokonezeke pa msonkhano. Yesani!
