Flexagon my. Indlela ukwenza yezandla-ntathu?

Amanqaku ezenziwe ngephepha - yinto ihlabathi lonke kweyantlukwano yendalo. emininzi amaphepha kusungulwe zezibalo. Umzekelo, eyaziwa lomnqweno yimfumba flexagon ehlabathini lonke nabo yasungulwa umfundi kwimathematika yasePrinceton University Arturom Stounom ngo-1939. Le flexagon eyonwabisayo? Indlela yokwenza ezahlukeneyo flexagon nokumkholisa abantwana?

A yezandla fun ngamaphepha

igama ezingeyomfuneko Latin (flectere), yenza isiseko igama, oko uzimisele okanye isongiwe. Ngoko ke flexagon - buyimilo, nto leyo iingenziwa ukusuka komcu eqhelekileyo yephepha emhlophe. ixesha ngasinye, ayeguqa polygon, sifumana inqwelo-moya entsha.

Flexagon ukuba kunjani? Indlela yokwenza oko ekunene kulo mzobo? Ngokwesiqhelo wenze flexagon ezinamacala tyaba, njengoko ilula. Ukusebenzisa iindidi iiphatheni kwezi moya, siya kumkholisa abantwana yezandla ezingaqhelekanga, nokubandakanya nabo ekudalweni zombini Planar kunye namanani volume nazo ziluncedo.

Flexagon: ukwenza njani iphepha?

ukuqala phi? Ngoko ke, siye sagqiba ukwakha flexagon. Indlela yokwenza uluhlu lomnqweno yimfumba ngokukhawuleza? Polygon ihamba ngokukhawuleza ngokulula ukusuka kuxwebhu olunye iphepha mhlawumbi, kodwa kuyacetyiswa ukuba ukukhetha ithambe kakhulu. Flexagon quadrangular ebizwa tetrafleksagonami. A mzobo ukuba elimile namacala, ebizwa geksafleksagonom. kumphezulu ngalinye namacandelo-6 oonxantathu yayo. Kunjalo kukho oktafleksagony (emacaleni 8) kunye dodekafleksagony (emacaleni 10). Njani flexagon kwephepha? Scheme zahlukahlukene kakhulu. Cinga nje indlela elula, nto leyo kwenziwa geksafleksagon zesiqhelo. Esi sikimu elisetyenziswa ngokufuthi.

Kulula ukuba bafunxe ngokwabo, kuba iqulathe kuphela liqela oonxantathu tye. Kodwa unako ukusebenzisa i scheme ornamented apho okokuqala kulula ukuba bahlanganisane bezandla. Xa wesekethe isikwe, agobe kunye nezigaba leaf eDibanisa okuninzi, beguqa unxantathu ngamnye ezenza inxenye moya eyahlukileyo. Xa flexagon ibandla ngokupheleleyo, uncamathelise iinkcukacha lokugqibela.

Kwi ngasinye kwezi iindawo ezine ziya kuba umzobo wakho. Emva kokufunda eli cebo, ngoko ungaya ukusebenza ngobuchule. On iphepha elingenanto zoba unxantathu efanayo. Ngoko ke inani amacandelo leyo ibe moya. Oonxantathu, ngokwemiyalelo, kufuneka sigobe, ukwenza polygon oyifunayo. Kodwa wonke umntu ukhetha indlela yabo, njengoko lula ngakumbi phinda. Ngokufanayo, le nkqubo iza naziphi yepholigoni emacala-flexagon. namacebo Okuninzi entsonkothileyo amanani kancane ngcono.

Leposi-flexagon

Mathematical umntwana imodeli-flexagon ngokuqinisekileyo uza kuba nomdla. Lo mhlaba emangalisayo lephepha singasebenza diversely. Kumphezulu amaqhekeza ezigqityiweyo ibonisa abalinganiswa cartoons zabantwana kwaye kunika ubungqina misebenzi umntwana ukuba imifuziselo zemathematika ukuze abe nomdla.

Kwaye uyakwazi ukuza kunye lokuposa obalaseleyo engaqhelekanga, yaye ayingomdlalo. Indlela yokwenza ikhadi-flexagon? Ukuba bezitsalele iindawo yamagama ebulisa ngomntwana kunye zokuhombisa iKrismesi, kuya kuba isipho gqitha uNyaka oMtsha. Ke wena, xa amanani ezimbi efunyenweyo, ukufumana enye indlela. Uyakwazi nje usike ukuphuma zakho ozithandayo umfanekiso noqhekeko ibe oonxantathu alinganayo, ngoko kufuneka ethe ngenyameko onke amacandelo obugcisa bezandla

iimveliso Bulk - ezahlukeneyo ukuvumelana

Kukho amanani-ntathu. Njani flexagon umthamo kwephepha? Ukuze wenze oku, uthabathe umzekelo icebo igqityiwe, equka triangles 10 alinganayo ukukhonza kumacandelo. Eli nani kuthiwa trigeksafleksagon - oko kukuthi, uninzi namacala iya kuba indawo ezintathu. Kakade ke, oku kumda. Le modeli isenokuba 4, 5, kunye imiphezulu, kunye 10. La flexagon nokuba ezinomdla kakhulu, nangona zisekelwe kwingcamango enye. Kodwa ukuba aqokelele ummangaliso onjalo ilula kakhulu. Umthetho ephambili xa ukwakha umfuziselo - landela imiyalelo. geksafleksagona Scheme 4 imiphezulu iza kukhangeleka ngolu hlobo:

Nanku umzekelo apho esiya nokuba busoyikisa nani - nonageksafleksagon. Oko kukuthi, flexagon umthamo kunye engile ezintandathu, kunye imiphezulu sele 9. Le yokudlala sele abadala, umntwana loo imodeli bunganongameli, kuyo nayiphi na imeko, ngaphandle koncedo lwabazali.

Ukuze siqonde nezo scheme ukuba umthamo izibalo kuya kuthatha ixesha. Le preform ingcono ukuhombisa kunye imibala eyahlukileyo ukunqanda uphazamiseko ngexesha ibandla. Zama!
