Tetrahedron ndiyo chimiro chakareruka kubva kumapurogoni. Iyo inoumbwa nezviso zvina, imwe neimwe yechipfuva chekufananidza, uye rumwe rutivi rwakabatanidzwa kune rumwe nerumwe chete chiso. Apo paunodzidza zvinhu zveizvi nhatu-maonero ejeriometric chimiro chekujekesa, zvakanakisisa kuita tethedhedron muenzaniso wemapepa.
Nzira yekubatanidza tetrahedron kubva papepa?
Kuvaka tetrahedron iri nyore kubva pamapepa, tinoda:
- chaiwo mapepa (dense, unogona kushandisa makadhibhodhi);
- protractor;
- mutongi;
- cise;
- adhesive;
- tetrahedron pepa, mufananidzo.
Nzira yebasa
- Tinotanga kushanda pane tetrahedron nekudhonza pepa pepa. Kana nhamba yacho yakarongwa kubva pamapepa akajeka, unogona kutora tsvina pairi.
- Isu tinotora rwonzi iyo iri chiso chetethedhedron. Kubva pamigumo miviri, tinoisa marangariro emakona makumi matanhatu evha, uye kuburikidza nemashoko akawanikwa, tora mitsetse yakarurama kusvikira vasangana. Isu tine unyanzvi wekufananidza.
- Zvadaro kune rumwe rutivi rwechetatu tinogadzira zvakafanana. Kubva pamagumo ose tinozodzoka zvakare 60 ⁰ uye tinosangana. Somugumisiro, chirongwa chinoumbwa nemakona mana ekufananidza anofanira kuwanikwa.
- Kuti mugadziriswe akabatanidzwa pamwechete uye kuwana tetrahedron, mumwe munhu anofanira kuita mamiriyoni 1 emiganhu pamativi matatu ematatu matatu akasiyana. Chigumisiro ichi chifananidzo.
- Bvisai scan uye muiname pamativi ose, ngatikotamirei zvipo mukati, kana zvichidikanwa, turai makona. Tinovashandisa glue uye tinoaisa kumativi emukati ezviso, tichibatanidza rwonzi rwepakati pakati pechipfuva uye mupiro pamwe nechepamusoro pekatatu pasina.
Zvimwe zvinowanikwa mazano:
- kana pepa racho rakaoma kwazvo, ipapo munzvimbo dzemafuro, iwe unofanirwa kubata chinhu chakasimba, somuenzaniso, kumucheto komutongi;
- kuitira kuti uwane tetrahedron yakasiyana-siyana, iwe unogona kupora zviso kana kuita kupisa pamashizha emapepa ane mavara.
Nzira yekuita tetrahedron kubva papepa musingaiti gluing?
Tinokutaurira tenzi weklasi umo inoudzwa kuti ingatanidza sei 6 tetrahedroni kubva pamapepa kusvika mumutsetse mumwechete uchishandisa nzira yekubva pakutanga.
Tinoda:
- 5 mapaundi emakese mapepa epepa yemarudzi akasiyana;
- cise.
Nzira yebasa
- Pepa rimwe rega rega rakakamurwa kuva zvikamu zvitatu zvakaenzana, kutema uye kuwana mabhanhire ane maitiro akaenzana ari 1 kusvika 3. Somugumisiro, tinowana mabhande makumi matatu, kubva kwatichawedzera mugovera.
- Tinoisa mutsara pamberi pedu tatarisana pasi, kutambanudza zvakananga. Tinowedzera hafu, tinofukura uye tinonamatira kusvika pakati pemucheto.
- Pamuganhu uri kurudyi, bendera kona kuti uite museve, uchitamise 2-3 cm kubva pamucheto.
- Saizvozvowo, bhenekera kona yakasara (chinyorwa sepepa kuita tetrahedron 3).
- Tinonamatira kona yepamusoro yekona yengoro duku, iyo yakazoguma semugumisiro webasa rekare. Nokudaro, mativi emuganhu wakapetwa achave akafanana.
- Wedzera pfupa rinoguma.
- Wedzerai kona yakasara uye pane yakatove iripo mapepa emaputi tivhare mukati mekona mukati sezvinoratidzwa mumufananidzo.
- Muchikona chakanakisisa, benderera kumusoro kwakadzika pasi kuitira kuti iparadzanise nekafu yakaitwa panguva yekushanda # 3.
- Rutivi rwekunze rwakaputirwa zvakare kurudyi uchishandisa pfu yakaitwa semagumisiro ekushanda nhamba 3.
- Mabasa ekutanga anodzokororwa kubva kune rumwe rutivi rwemucheto, asi kuitira kuti zviduku zviduku zvioneke pamagumo akafanana emutsara.
- Mucherechedzo unogadziriswa unoiswa mukati hafu pamwe nekureba uye uite kuti uve mbeveve uone pachena. Nzira chaiyo yekuzivisa ichazojeka gare gare, apo muenzaniso wacho pakupedzisira wakaungana. The element yakagadzirira, iye zvino tinoita 29 zvimwe nenzira imwecheteyo.
- Chibatanidzwa chacho chinoshandiswa kuitira kuti panguva yegungano rayo rutivi rwavo rwokunze ruonekwe. Isu tinobatanidza hutano huviri nekuisa tabhi muhomwe inoumbwa nekona kadiki mukati.
- Sangano rinobatanidza rinofanira kugadzira sendima ye 60 ⁰, iyo iyo dzimwe hukama huchabatana (mufananidzo sekuita mapepa tetrahedron 13).
- Tinowedzera chechitatu chekubatanidza kune yechipiri, uye yechipiri inosangana neyokutanga. Kuguma kwechimiro ichi chinowanikwa, pamusoro pazvo zvese zvitatu zvayo zvinosanganiswa.
- Saizvozvowo, wedzera zvitatu zvimwe. Yekutanga tetrahedron yakagadzirira.
- Nzira dzomukati yakapedzisira dzingave dzisinganyatsofanana, saka kuti zvive zvakakwana zvakakwana, munhu anofanira kusiya achizarura mavhesi evanhu vose vanotevera tetrahedra.
- Pakati pavo maetrahedroni anofanira kubatanidzwa kuitira kuti imwe yerimwe inopfuurira nepakati pehuni mune imwe.
- Vatatu vatrahedra vakabatana pamwechete.
- Four tetrahedra yakabatana pamwechete.
- Muchina wevetrahedroni mashanu wakagadzirira.

Kana iwe wakakunda ne tetrahedron, unogona kuramba uchiita mapepa, icosahedron , parallelepiped uye mamwe mazita ejometri kubva pamapepa .
