Kodi mungapange bwanji tetrahedron pamapepala?

Tetrahedron ndi chiwerengero chosavuta kuchokera ku polygoni. Zimakhala ndi nkhope zinayi, mbali iliyonse yomwe ili ndi katatu, ndipo mbali iliyonse imagwirizanitsa ndi nkhope imodzi yokha. Pomwe mukuphunzira zofunikira za chiwerengero chajimidwe chojambulachi, ndi bwino kupanga chitsanzo cha tetrahedron.

Kodi mungagwiritse ntchito bwanji tetrahedron pamapepala?

Pofuna kupanga tetrahedron yosavuta pamapepala, timafunika:

• pepala lenileni (wandiweyani, mungagwiritse ntchito makatoni);
• chithandizo;
• wolamulira;
• mkasi;
• chomatira;
• tetrahedron ya pepala, chithunzi.

Chifukwa cha ntchito

1. Timayamba kugwira ntchito pa tetrahedron polemba pepa. Ngati chiwerengerocho chikukonzekera kuchokera pa pepala lapaderalo, mukhoza kuyang'ana molunjika pa izo.
2. Timayang'ana mzere womwe uli nkhope ya tetrahedron. Kuchokera kumapeto awiri, ife timayika pambali makilomita 60 ⁰, ndipo kupyolera muzomwe tapeza, tambani mizere yolunjika mpaka iwo atadutsa. Tili ndi katatu kamodzi.
3. Kenako kumbali iliyonse ya katatu, timapanga chimodzimodzi. Kuchokera pa mapeto onse timabwereranso 60 ⁰ ndikugwirizanitsa. Chotsatira chake, muyenera kupeza ndondomeko yokhala ndi zing'onozing'ono zinayi zokhala ndi katatu.
4. Pofuna kuti galimoto ikhale yosakanikirana ndi kupeza tetrahedron, munthu ayenera kupanga mapaundi 1 masentimita pambali zitatu za katatu. Chotsatira ndicho kujambula.
5. Dulani chingwecho ndikuchikombera pamitsinje yonse, tiyeni tiweramitse mphotho, ngati kuli kofunika, tipeze ngodya. Timawagwiritsira ndi guluu ndi kuwasindikiza kumbali ya nkhope, kuphatikizapo khola pakati pa mbali ndi gawo ndi mbali ya katatu.

Zina zowonjezera:

• Ngati pepalali ndi lolimba kwambiri, ndiye m'malo amtundu, muyenera kugwira chinthu cholimba, mwachitsanzo, pamphepete mwa wolamulira;
• Kuti mupeze tetrahedron yamitundu yosiyanasiyana, mukhoza kujambula nkhope kapena kufotokoza pamapepala ofiira.

Kodi mungapange bwanji tetrahedron pamapepala popanda kugwedeza?

Tikukufotokozerani kalasi ya mitu yomwe imauzidwa momwe angasonkhanitsire tetrahedroni 6 kuchokera pamapepala kukhala gawo limodzi pogwiritsa ntchito njira ya origami.

Tifunika:

• Mapaundi awiri a mapepala apamwamba a mitundu yosiyanasiyana;
• lumo.

Chifukwa cha ntchito

1. Pepala lirilonse ligawanika kukhala magawo atatu ofanana, kudula ndikupeza magulu omwe mbali yake yayamba ndi 1 mpaka 3. Chifukwa chake, timapeza magulu 30, omwe tidzawonjezerapo gawoli.
2. Timayika mzere kutsogolo kwa ife pansi, kutambasula pang'onopang'ono. Timapindikiza theka, kufalikira ndi kugwadira pakati pamphepete.
3. Pamphepete mwachindunji, gwedezani ngodya kuti mupange mtsinje, ndikusunthira 2-3 masentimita pambali.
4. Mofananamo, gwirani ngodya kumanzere (chithunzi ngati pepala kuti mupange tetrahedron 3).
5. Timakongoletsa ngodya yapamwamba ya katatu, yomwe inatuluka chifukwa cha ntchito yapitayi. Choncho, mbali zonse za m'mphepete mwake zidzakhala pambali yomweyo.
6. Lonjezerani zotsatirazi.
7. Lonjezani ngodya ya kumanzere ndi mizere yomwe ilipo kale pindani pakona mkati monga momwe zasonyezera mu chithunzi.
8. Mu ngodya yolondola, pendani pamwamba pamtunda pansi kuti mutsegulire ndi khola lomwe lapangidwa pa ntchito # 3.
9. Mbali yakunja imakulungidwa kumanja pogwiritsa ntchito khola lopangidwa chifukwa cha ntchito nambala 3.
10. Ntchito zam'mbuyomu zikubwerezedwa kuchokera kumapeto ena a mzerewu, koma kuti zochepa zazing'ono ziwoneke pamapeto a mzerewo.
11. Chotsatiracho chimapangidwa mu theka limodzi ndi kutalika ndipo chilole icho chimveke kuti chidziwuluke pokhapokha. Njira yeniyeni yofotokozera idzawonekera bwino pakapita nthawi, pamene pamapeto pake padzakhala msonkhano. The element ali okonzeka, tsopano tikuchita 29 ena mofanana.
12. Chiyanjanocho chimasinthidwa kotero kuti pa msonkhano wake mbali yake ikuwoneka. Timagwirizanitsa zigawo ziwiri poika kabati mu thumba lopangidwa ndi ngodya yaing'ono.
13. Mgwirizano wokhudzana uyenera kukhazikitsa mbali ya 60 ⁰, pansi pazimene maulumikizano ena adzalumikizana (chithunzi ngati kupanga pepala tetrahedron 13).
14. Timaonjezera gawo lachitatu lachiwiri, ndipo chachiwiri chikugwirizana ndi choyamba. Mapeto a chiwerengerocho amapezeka, pamwamba pake momwe maulumikizano ake onse akugwirizanitsidwa.
15. Mofananamo, onjezerani zina zowonjezera zitatu. Tethedhedron yoyamba yakonzeka.
16. Mitsempha ya chiwerengero chotsirizidwayo sichikhoza chimodzimodzi, kotero kuti muyenerere molondola, munthu ayenera kusiya kutsegula makondomu amtundu uliwonse wa tetrahedra.
17. Pakati pawo ma tetrahedroni ayenera kugwirizanitsidwa kotero kuti mbali imodzi imadutsa mu dzenje lina.
18. Ma tetrahedra atatu adagwirizanitsidwa palimodzi.
19. Tetrahedra zinayi zogwirizana.
20. Mutu wa tetrahedroni zisanu ndi wokonzeka.

Ngati mwalimbana ndi tetrahedron, mukhoza kupitiriza ndikupanga digm , icosahedron , maulendo ophatikizana ndi ena ojambula pamtundu.
