Lub dodecahedron yog lub duab multifaceted geometric uas muaj kaum ob pentagons. Txhua peb pentagons tsim ib qho ntawm cov kab saum toj ntawm cov duab sib txawv no. Niaj hnub no, lub dodecahedron feem ntau siv rau hauv kev lag luam ntawm ntau yam khoom plig thiab daim qhia hnub hli.

Nws yog qhov tsim nyog

  • - dodecahedron layout;
  • - txiab;
  • - tus pas ntsuas;
  • - kua nplaum;
  • - cim cim;
  • - daim ntawv;
  • - xaum;
  • - ntawv;
  • - ntawv xaj.

Cov Lus Qhia

Kauj ruam 1

Yuav cov ntawv qhia hnub npaj-txiav dodecahedron-puab thiab sib sau ua ke. Nws tsis yog ib qho nyuaj kom tau txais cov duab zoo li no. Ua tib zoo txiav cov duab raws tus cwj ciam. Tom qab ntawd, siv tus pas ntsuas, quav dodecahedron ntawm nws cov folds (lawv tau qhia nrog kab ntawv dotted) thiab kua nplaum. Npog txhua yam ntawm cov scuffs thiab cov khoom siv pom me me pom nrog lub cim ntawm cov xim tsim nyog.

Kauj ruam 2

Ua kom dodecahedron. Txhawm rau pib, quav cov Whatman ntawv nyob hauv ib nrab nrog txoj kab nqes me me. Ntawm ib daim duab los qhia, kos ib lub pentagon rau hauv nruab nrab, thiab tom qab ntawd kos lwm tus pentagon los ntawm txhua ntug. Qhov no yuav xaus nrog rau (pentagons) kos. Perekolit koj cov txuj ci thib ob ntawm daim ntawv Whatman thiab kos cov duab muaj tseeb. Tom qab ntawv kos cov ntsiab lus gluing. Thaum ua tiav kev ua haujlwm tiav, txiav tawm cov kab ntawv, xim thiab kua nplaum nws.

Kauj ruam 3

Yuav peb caug daim ntawv (koj tuaj yeem siv peb xim ntawv ntawm kev zoo nkauj). Siv peb nplooj ntawv ua ke thiab ua cov qauv tawm ntawm lawv. Txhawm rau ua qhov no, quav cov ntawv ua ib nrab, tom qab uas txhua tus ib nrab dua ib nrab (thim rov qab). Ntawd yog, qhov txiaj ntsig yuav tsum yog tus kiv cua. Quav ntawm txhua sab xwm meem thiab qhov module me ntsis obliquely. Ib qho txawv trefoil module yog qhov kawg ntawm koj dodecahedron. Txuas ntxiv lub tsev nrog cov seem nyob rau nees nkaum xya nplooj ntawv. Tsuas yog thaum kawg ntawm kev sib dhos yuav ua lub cim ruaj khov, yog li thaum muaj tswv yim zoo, siv cov ntawv xaj rau kev yooj yim dua
