Ukudala ezobugcisa ngezandla zabo kungonakali nje kuphela kubantwana, kodwa abadala. Nangona kunjalo, kubantu abadala, inani elaneleyo leemodeli liyilwe, ehluke kwiinkqubo eziyinkimbinkimbi yokuphunyezwa kunye nexesha elichithwe ekudalweni kwazo. Kungekudala, abantu abadala kunye nabantwana banomdla ekudaleni amanani e-geometric ezinzima. Kule fom yamanani yi-icosahedron, eyona ipoloni rhoqo kwaye yenye yezilwanyana zasePlato - i-polyhedra eqhelekileyo. Lo mfanekiso unobuso obunxantathu obunxantathu (ama-triangles equilateral), iimilo ezingama-30 kunye nama-vertices angama-12. Ikosahedron efanelekileyo yephepha kunzima ukuqokelela, kodwa inomdla. Ukuba unomdla kwi-origami, ukwenza iphepha le-icosahedron ngezandla zakho akuyi kuba nzima. Yenziwe ngamaphepha anemibala, i-corrugated paper, foil, iphepha lokupakisha yeentyatyambo. Ukusebenzisa izixhobo ezahlukeneyo, unokwenza ubuhle kunye nobuhle obukhulu kwi-icosahedron yakho. Yonke into incike kuphela kwingcamango yomdali wayo kunye nezinto eziphathekayo etafileni.

Sinikela ngeenguqu eziningana ze-icosahedron izicatshulwa ezingaprintwa, zidluliselwe kwiphepha eliqingqiweyo kunye nekhadibhodi, zijikeleze kunye nemigca kunye kunye.

Indlela yokwenza i-icosahedron yephepha:
Ukuze udibanise i-icosahedron kwiphepha okanye iphephabhodi, kufuneka ulungiselele izinto ezilandelayo kusengaphambili:
- ukuhleka kwe-icosahedron;
- glue PVA;
- izikiti;
- umlawuli.
- Phrinta ukuhleka kwe-icosahedron kwisiqwenga samaphepha.
- Sika ngeempumlo. Oku kuyimfuneko ukwenzela ukuba ube nendawo yokukhulula ukuhlanganisa iindawo kunye. Kubalulekile ukunqumla i-icosahedron ngokukhawuleza kangangoko kunokwenzeka, kuba ekutshintshiseni okuthe kancinci i-artifact ekugqibeleni iya kubonakala ingalunganga. Le mfuneko yokwehliswa okuchanekileyo ngenxa yokuba zonke i-triangles kwi-icosahedron zinamacandelo afanayo, kwaye ukuba nayiphi na icala liyahlukahluka ngobude, ekugqibeleni ukungafani ngokukhulula kuya kubamba isohlo.
- Siyifaka i-icosahedron kwimigca eqinile.
- Ngoncedo lweglue siyazibandakanya iindawo ezichazwe ngumgca odibeneyo, kwaye uqhagamshelanise amacala angamakhelwane. Kufuneka ukuba ubambelele kwimeko enamacandelo angama-20 ukulungiswa komninzi. Ngokufanayo, kufuneka uqoqe onke macala e-icosahedron. Iimbambo ezimbini zokugqibela zimela ubunzima obukhulu ekukhonkeleni, kuba zifuna ubuchule kunye nomonde. Icosaedr ikulungele.
Xa udala i-icosahedron, kubalulekile ukuhlawula ingqalelo kwinkqubo yokuguqa zonke iinkcukacha: ukuze ugobe iphepha, unokusebenzisa umlawuli oqhelekileyo.
Kuyaphawuleka ukuba i-icosahedron inokufumaneka kwimihla ngemihla. Ngokomzekelo, ibhola yebhola eyenziwa ngendlela yekhosahedron elinezithathu (i-polyhedron eneepentagon ezili-12 kunye nama-hexagon angama-20 ejongwa rhoqo). Oku kubonakala ngokukodwa xa upopera i-icosahedron ebangelwa emnyama nangomhlophe, njengebhola ngokwayo.

Ibhola lebhola ekwenziweyo ingenziwa ngokuzimeleyo ngokushicilela ukutshekisha kokuqala kwekhosahedron ekhohliweyo kwiikopi ezi-2:
Ukudala i-icosahedron ngezandla zakho yinto enomdla efuna ukucinga, umonde kunye nephepha elininzi. Nangona kunjalo, isiphumo esiyifumene ekupheleni siya kukukholisa iliso ixesha elide. I-icosahedron inokunikezwa ukuba idlale kumntwana ukuba sele sele efikelele kwiminyaka emithathu. Ukudlala ngolo hlobo oluyinkimbinkimbi yejometri, uya kuhlakulela ingcinga nje, izakhono zendawo, kodwa uyaziqhelanisa nehlabathi lejometri. Ukuba umntu omdala unqume ukwenza i-icosahedron eyedwa, ngoko inkqubo yokudala yokwakhiwa kwe-icosahedron iya kuvumela ixesha ukuba lidlule, kwaye liyaziqhayisa ngamandla akhe okudala ukwenza amanani anzima.
