Ukwakha izandla ngezandla zabo akuthakali kuphela izingane, kodwa kubantu abadala. Kodwa-ke, kubantu abadala, inomboro eyanele yamamodeli asungulwa, ahluke ekubunjeni kokuqaliswa kanye nesikhathi esichithwa ekudalweni kwazo. Muva nje, abadala nabantwana banesithakazelo ekudaleni izibalo ze-geometric eziyinkimbinkimbi. Kulolu hlobo lwezinombolo yi-icosahedron, okuyinto i-polygon ejwayelekile futhi ingenye yama-solids asePlato - i-polyhedra evamile. Lesi sibalo sinobuso obungunxantathu obungama-20 (ama-triangal equalateral), amaphethelo angu-30 kanye nama-vertices angu-12, okuyiwona ohlangothini lwezimbambo ezingu-5. I-icosahedron yephepha elungile kunzima ukubutha, kodwa kuyathakazelisa. Uma unesithakazelo ku-origami, bese wenza iphepha le-icosahedron ngezandla zakho ngeke kube nzima. Yenziwe ngembala enemibala, ephepheni, foil, iphepha lokupakisha lezimbali. Ukusebenzisa izinto ezihlukahlukene, unganika ubuhle obuningi nobuhle obukhulu ku-icosahedron yakho. Konke kuncike kuphela emcabangweni womdali wayo kanye nezinto eziphathekayo etafuleni.

Sinikeza izinguqulo eziningana ze-icosahedron izikrini ezingahle zinyatheliswe, zidluliselwe ephepheni elibhaliwe nekhadibhodi, zibophe imigqa futhi zihlanganiswe ndawonye.

Indlela yokwenza i-icosahedron yephepha:
Ukuze uhlanganise i-icosahedron ephepheni noma ephepheni, kufanele ulungise izinto ezilandelayo kusengaphambili:
- ukuhleka usulu kwe-icosahedron;
- glue PVA;
- isisindo;
- umbusi.
- Phrinta ukuhleka kwe-icosahedron ephepheni.
- Sika ngezimpawu zokubhala. Lokhu kuyadingeka ukuze ube nendawo yamahhala yokuhlanganisa izingxenye ndawonye. Kubalulekile ukusika i-icosahedron kancane kancane ngangokunokwenzeka, ngoba kancane kancane ushintshe i-artifact ekugcineni izobukeka kabi. Lesi sidingo sokusika okunembile kungenxa yokuthi zonke izintathu ezinqoleni ze-icosahedron zinezinhlangothi ezifanayo, futhi uma kunoma yiluphi uhlangothi luzohluka ngobude, ekugcineni ukungafani okunjalo ngosayizi kuzobamba iso lakho.
- Sifaka i-icosahedron emigqeni eqinile.
- Ngosizo lwe-glue sihlanganisa izindawo ezihlanjululwe ngumugqa odibeneyo, bese uxhuma izinhlangothi ezizungezile zezintathu. Kudingekile ukuba ubambe kuleso simo uhlangothi olulodwa oluhlanganiswe imizuzwana engu-20 ngokulungiswa okunamandla. Ngokufanayo, udinga ukuhlanganisa zonke izinhlangothi ze-icosahedron. Izimbambo ezimbili zokugcina zimelela ubunzima obukhulu kakhulu ekubambisaneni, ngoba zidinga ikhono nokubekezela. Icosaedr isilungile.
Uma udala i-icosahedron, kubalulekile ukukhokha ngokukhethekile inqubo yokuguqa yonke imininingwane: ukuze ugobe ngokufanayo iphepha, ungasebenzisa umbusi ojwayelekile.
Kuyaphawuleka ukuthi i-icosahedron ingatholakala futhi ekuphileni kwansuku zonke. Isibonelo, ibhola lebhola lenziwa ngesimo se-icosahedron esinezintambo (i-polyhedron enama-pentagon angu-12 nama-hexagon angu-20 ajwayelekile). Lokhu kubonakala ngokucacile uma upenda i-icosahedron ephumela emnyama nasemhlophe, njengebhola ngokwayo.

Ibhola lebhola lezinyawo lingenziwa ngokuzimela ngokunyathelisa ukuskena kokuqala kwe-icosahedron emithathu emakhophi:
Ukudala i-icosahedron ngezandla zakho kuyindlela ethakazelisayo edinga ukucabanga, ukubekezela kanye nephepha eliningi. Noma kunjalo, umphumela owatholile ekugcineni uzojabulisa iso isikhathi eside. I-icosahedron inganikezwa ukudlala kwengane uma isifinyelele eminyakeni engamashumi amathathu. Ukudlala ngesimo esiyinkimbinkimbi se-geometri, ngeke athuthukise ukucabanga okucabangelayo, amakhono wendawo, kodwa futhi azijwayele izwe lejometri. Uma umuntu omdala ethatha isinqumo sokwakha i-icosahedron eyedwa, inqubo enjalo yokudala yokwakhiwa kwe-icosahedron izovumela isikhathi ukuba sidlule, futhi siziqhayise ngamandla akhe okudala ukwenza izibalo ezinzima.
