Kurumi: How kuita dodecahedron yakagadzirwa bepa

Dodecahedron - a polyhedron zvinosanganisira 12 fanana pentagons. Izvi mufananidzo zvitsigiro yakatarwa ndege kubva pakombiyuta makarenda kuti openwork akarembedzwa matochi.

How kuti dodecahedron yakagadzirwa mapepa?

Unogona kuvakira muzviitire nePentagon - zviri nyore uye anovimbisa kumusoro nemazvo mufanidzo. Kuvaka nguva dzose nePentagon vachada nekambasi uye mutongi. Swedera denderedzwa zvinodiwa saizi. Shandisa kwese nharaunda. Kuita rimwe perpendicularly kwazviri nharaunda. Ipapo mumwe radii rakakamurwa zviviri zvakaenzana zvikamu. hafu nerimwe richava yakasiyana nharaunda, duku denderedzwa, izvo achaita basa webetsero. Next, batanidza Nhongonya ebetsero denderedzwa kunzvimbo inokosha denderedzwa nharaunda intersects mumwe (somuenzaniso, panguva A). Kunoguma mutsetse kuchaita piringisha hwebetsero denderedzwa pane imwe nguva - B. The kure AB mumwe-chegumi denderedzwa. Ndizvo mufambo nekambasi unotara pamusoro nechigadziko denderedzwa, uye ipapo batanidza pfungwa idzi yakarurama mitsetse kuburikidza nomunhu - nguva dzose nePentagon akagadzirira!

Pane dzimwe nzira. Somuenzaniso, mumwe nePentagon inogona kuvakwa uchishandisa protractor, asi hakurevi kururama kwayo. Most Rehi nzira - kutora vakagadzirira akagadzirwa zano, kudhinda, uye nokuda kwaizvozvo, "muenzaniso" chava tinkering rwerudyi bepa ounyanzvi. Asi nzira iyi, kunyange nyore, hazvisi nguva dzose akakodzera - nekuti dzimwe nguva unofanira kuita dodecahedron imwe saizi. Unogona kuwedzera imwe nePentagon kune kutsvakwa kukura uye kudhinda iye chete, zvino avake mufananidzo pamusoro chiripasi.

Asi "muenzaniso" - haasi kugadzirira Hack asi. How kuti dodecahedron yakagadzirwa mapepa? Izvi zvinoda:

1. Paper dzakakodzera arambe achirema. Hazvifaniri kuva zvakanyanya mutete kana akanyanya gobvu - zvinganaka 220 g / m², ine arambe achirema paperboard, izvo inotengeswa seti vana. Kunyange zvazvo iri rakagadzirwa gobvu makadhibhokisi ingangodaro kusika-dimensional matatu dzemitambo, iwe chete unofanira kwerubwinyo rwakagara rwuripo-muitiro pazvirugu zvose - snick kana kusunda yakanaka, kuti vane zvakanaka uye zvakaenzana guda.

2. chigero, penzura, guruu, tsono knitting kana banga Stationery

Mazano kuita dodecahedron

Paper iri muboka iri waifadza zvishoma kuvaparadzanisa tsono, ivo kungopotsera rutivi Stationery banga kana chinhu unopinza asi kwete achicheka. Akashambidzika pazvirugu sandara - hafu kubudirira.

Kana guruu haasi pedyo, kuti dodecahedron inogona vakaunganidza, somunhu constructor, kuita incision achitevedza crease uye ipapo nyore kuisa chikamu kupinda mumwe.

Kana iwe vatore dodecahedron mu modular unyanzvi (mirayiridzo pazasi), ipapo majoini yakanaka prokleivat kana zvinodyiwa kugadzirisa, sezvo mamiriro anova akatsiga chete pashure kugadzira wokupedzisira module.

Dodecahedron mu Kurumi unyanzvi

Module Kurumi - rakaisvonaka panobva dodecahedron. How kuti dodecahedron kubva papepa pane modular nzira? 30 vanofanira kuva rectangular kana mativi mapepa. Imwe neimwe mapepa kuputirwa hafu, ipapo mumwe nomumwe hafu kufonyora negwara risiri - zvichadaro "akodhiyoni" iri kuwedzererwa mana. Dzimwe nguva, kana jira haasi square, kuita "harmonica" muna matatu Kuwedzera. Somugumisiro zvaunazvo mumaoko rakamanikana kanyika kuti promougolnaya. Zvadaro, musi mumwe kurutivi rectangle achitevedza rakamanikana divi flexing nzvimbo. Makona vari akaumba imwe nhungamiro - remangwana fastening kuti refueled mu "harmonica". Zvadaro zvakabaya module nechomukati slant Tsanga yacho yaichekwa kubva makona kurutivi duku. Saka, mumwe module Kurumi dodecahedron - a-dimensional matatu, chinosanganisira miviri yehombodo uye makona mufananidzo remangwana. Apo vose modules zvakagadzirira, unogona kutanga ungano.

Ungano rinotanga raiva pedyo nebundu chete iyo uchida kutora modules matatu. The mufananidzo pazasi ari mutema, pink yellow Kurumi dzi. Assembly chati chaizvo nyore, uye nhamba dzakadaro kunogona kubata nyore kunyange ruzivo.

Chii Crafts zvinogona kuitwa maererano munhu dodecahedron?

divi imwe neimwe dodecahedron akaita mapepa - munhu sandarara nePentagon, izvo pachazvo zvinogona hwaro-siyana uye noshamisa siyana. Somuenzaniso, muna Photo pazasi nePentagon chikatsiviwa shanu-wakananga nyeredzi. Mbabvu mumufananidzo uyu havasi iripo, kunyange zvinofungirwa. How kuti dodecahedron yakagadzirwa bepa chairatidzika nyeredzi? Tsiva iri kutsvaira, kuratidzwa pamusoro apa, nePentagon nomumwe zvaida shanu-rwakavakwa mufananidzo uye batanidza akasavawana mbabvu uye pamisoro.

In pikicha iyi rinotaurwa stellated dodecahedron. At mwoyo nomumwe "danda" chichiri chete nePentagon.

chero volumetric chimiro ingangoumbwa panzvimbo pentagonal mapiramidhi.

In mufananidzo pazasi sezvo pentagons kuita zvakawanda kunzwisisa Kurumi nematunhu, izvo vanofarira unyanzvi ichi chinogona kuwanikwa mumabhuku.

Chero zvazvingava, kukura kunyange nyore gungano vanoronga dodecahedron kare kupa mikana zvikuru okugadzira zvinhu uye kuwana pachavo mikana yavo.
