Jambulani polyhedron kulumikiza. Jambulani stellate polyhedron

A zinthu zambiri zosangalatsa mungapeze Mthandizi m'madera a sayansi, yomwe zikuoneka konse imathandiza mu moyo watsiku ndi anthu wamba mu msewu. Mwachitsanzo, Masamu amene kwambiri akukuwerengerani yekha pazipata sukulu. Koma mwachirendo sankadziwa sayansi ndi yosangalatsa kwambiri, ngati anakumana nawo kwambiri. Kuti zojambula polyhedron jambulani - chinthu zosafunika kwathunthu pamoyo - akhoza kukhala chiyambi cha zinthu zosangalatsa, luso mumpanda ana ndi akulu omwe.

wokongola masamu

Azikongoletsa mkati mwa nyumba, kupanga manja awo zachilendo, zinthu wotsogola - ndi ntchito yosangalatsayi. Pangani zanu mwa kumanga pepala polyhedra zosiyanasiyana - zikutanthauza kuti akonze zinthu wapadera kuti akhoza kukhala chibwana kwa tsiku kapena awiri, koma akhoza kukhala mlengi mkati zokongoletsa. Komanso, ndi chitukuko cha luso angathe okhudza malo mawerengeredwe mitundu yonse ya zinthu, zikanakhala zotheka kuti akonze wotsogola ndi moyo m'nthawi ya 3D-zitsanzo. Pali amisiri amene ntchito prostroeniya chikusesa pansi pa malamulo a masamu anapanga zitsanzo pepala la nyama ndi zinthu zosiyanasiyana. Koma ichi ndi m'malo ovuta masamu ndi zojambula chilengedwe. развертка многогранника. Yambani ntchito mu phula adzakhala aone polyhedron.

Osiyana nkhope - zosiyanasiyana

Polyhedra - wapadera dera Masamu. Iwo ali ophweka - mwachitsanzo cubes, ana kusewera kuyambira ndili wamng'ono - ndipo pali kwambiri, zovuta. достаточно сложной областью конструирования и творчества: нужно не только знать основы черчения, геометрические особенности пространства, но и иметь пространственное воображение, позволяющее оценить правильность решения еще на стадии проектирования. Prostroenie chindodo polyhedra kulumikiza imatengedwa kuti ndithu malo ovuta ya kapangidwe ndi zilandiridwenso: ayenera osati kudziwa ndizosowa zojambula, makhalidwe zojambula za danga, komanso ndi m'maganizo okhudza malo, amene amalola kuti asa- kulondola mlandu pa siteji kapangidwe. Koma sangathe kuchita zongopeka. Kuti chindodo polyhedra pepala, si kokwanira kulingalira momwe mapeto Chioneke ntchito. Izo ziyenera kukhala wokhoza molondola kuwerengera, kumanga ndi mwaluso kudzatunga.

Woyamba polyhedron - kyubu

Ambiri mwina, aliyense kusukulu, ngakhale mu makalasi pulayimale sukulu kudutsa ntchito ntchito, chifukwa cha umene ukuyenera kukhala pepala kyubu. развертки многогранника куба на плотной бумаге со специальными кармашками, предназначенными для склеивания граней модели в единое целое. Nthawi zambiri, mphunzitsi anagawira preform - kuyang'ana kyubu polyhedron pa pepala wakuda ndi matumba wapadera, anafuna kulumikiza chitsanzo loyang'anizana pamodzi. ntchito imeneyi ophunzira pulayimale akhoza kunyadira, chifukwa ndi thandizo la pepala, lumo, zomatira, ndi khama lawo kuti chidwi bokosilo - atatu azithunzi omwe tikunena kyubu.

ndimasewera zobvuta

N'zosadabwitsa kwambiri zokhudza dziko safuna sukulu, koma pamene n'zotheka kupeza mwa iwo chinachake chidwi zimene angapereke chinthu chatsopano ndi zachilendo mu moyo bwino. Osati akulu ambiri amakumbukira kuti polyhedra chomwecho anawagawa nambala yaikulu mitundu ndi subspecies. Mwachitsanzo, pali otchedwa Plato zolimba - otukukira kunja polyhedra, wopangidwa yekha wa polygons zonse. matupi amenewa ali ndi zaka zisanu zokha kuti: tetrahedron, octahedron, hexahedron (kyubu), icosahedron, dodecahedron. Iwo akuyimira mawonekedwe otukukira kunja popanda cavities. Star woboola pakati polyhedra wapangidwa akalumikidzidwa zazikulu mu masanjidwe zosiyanasiyana. развертка многогранника простого позволяет нарисовать, вернее начерить, а затем и склеить из бумаги звездчатый многогранник. Choncho, losavuta jambulani wa polyhedron pa zochitika kudzatunga m'malo nacherit, kenako kumata mapepala stellate polyhedron.

Zonse ndi osasamba stellate polyhedra

Kuonjezera zolimba Plato pamodzi mu dongosolo linalake, mukhoza kuyamba kwambiri a nyenyezi mnogorannikov - wokongola, zovuta, Mipikisano chigawo. Koma adzatchedwa "osasamba stellate polyhedra". Kumanja stellate polyhedra ndi anayi okha: ang'ono stellated dodecahedron lalikulu stellated dodecahedron, dodecahedron lalikulu ndi icosahedron kwambiri. Kuyang'ana polyhedra kulumikiza sadzakhala zojambula yosavuta. Iwo, monga kanjedza adzapangidwa zigawo zikuluzikulu zingapo. Mwachitsanzo, ang'ono stellated dodecahedron inamangidwa ku 12 pentagonal isosceles piramidi wapangidwa ndi mtundu wa dodecahedron zonse. Ndiko, kwa kuyamba adzakhala kudzatunga ndi kumata 12 zidutswa zofanana mapiramidi zonse wapangidwa 5 mbali ofanana. Ndiyeno mmodzi apangidwe nyenyezi woboola pakati polyhedron. Aone zing'onozing'ono stellate dodekaera - zovuta ndi kovuta ntchito. Prostroen kwa izo, muyenera kukhala ongokwana M'ndegeyo olumikiza mzake matupi 13 mapanga sikani zosiyanasiyana zojambula buku.

Kukongola mu kuphweka

thupi lonse voluminous anamanga malinga ndi malamulo a masamu, adzayang'ana chidwi, kuphatikizapo polyhedron nyenyezi woboola pakati. Jambulani aliyense mchitidwe thupi aliyense ayenera kuchitika monga momwe akanathera. Ndipo ngakhale losavuta volumetric polyhedra, kuyambira Myuda tetrahedron - kukongola chodabwitsa cha chiyanjano cha chilengedwe ndi ntchito anthu zopezeka chitsanzo pepala. Apa, mwachitsanzo, mosalekeza kwambiri za Plato otukukira kunja polyhedra - dodecahedron. развертки правильных многогранников для склеивания, нужно приложить максимум аккуратности и внимательности. Izi chithunzi zojambula 12 ndi nkhope mwamtheradi zofanana, 30 m'mbali ndi 12 chindodo vershin.Chtoby polyhedra zonse kulumikiza, m'pofunika khama chisamaliro pazipita ndi chidwi. Ndipo ikuluikulu kukula kwa zimakwana bwino ayenera kukhala miyezo onse.

M'mene tingamangire jambulani anu?

Mwina, kuwonjezera pa mgwirizano wa polyhedron ndi - ngakhale stellate, ngakhale Plato - kwambiri chidwi kumanga zitsanzo tsogolo aone awo, potaya lokonza awo chifukwa chojambula, kapangidwe ndi okhudza malo voobzheniyu. Zambiri platonovstkie matupi ndi lopangidwa polygons yosavuta, zomwe mu mawonekedwe amodzi ofanana ndi mnzake. Mwachitsanzo, tetrahedron - atatu isosceles Triangles. Pamaso prostroen jambulani, muyenera kuona mmene kuti pindani polygons mosabisa ndi mzake kuti alandire polyhedron. Triangles akhoza olumikizidwa kwa wina ndi mnzake mu nthiti mwa kuyandikira pafupi wina ndi mnzake. Kulumikiza polyhedra zikulilima dera ayenera kupatsidwa matumba wapadera kapena kutseka kuti uchiwo usatuluke kuti amaphatikana mbali zonse mu lonse. Tetrahedron - chabe chithunzi cha nkhope zinayi. Octahedron akhoza ankayimiridwa ngati tetrahedron awiri, ali eyiti Garnier - isosceles Triangles. Hexahedron otchedwa bwino kwa onse kuchokera kyubu mwana. Icosahedron ndi pawiri 20 isosceles Triangles abwino polyhedron otukukira kunja. Dodecahedron - ndi volumetric chithunzi cha mbali 12, omwe ndi zonse Pentagon.

chipango chabwino

Amange polyhedron developable ndi zomatira pepala chitsanzo cha izo - nkhani wosakhwima. Jambulani, ndithudi, inu mukhoza kutenga okonzeka zopangidwa. Ndipo n'zotheka, kutsatira uslily, kumanga nokha. Koma kuti apange zonse atatu azithunzi omwe tikunena polyhedron chitsanzo, muyenera chisiyeni. polyhedron A bwino anachita ku pepala wandiweyani amene wagwirizira mawonekedwe ake bwino, ndipo sachita kuwalepheretsa ku zomatira ndi. mizere onse kuti ndichotse, ndi bwino Pre-Kankhani, ntchito Mwachitsanzo, nepishuschuyu ballpoint cholembera kapena kumbuyo kwa tsamba mpeni. nuance Izi zingathandize chitsanzo alipo molondola kwambiri, kugwilizana ndi kukula ndi malangizo a nthiti.

Ngati inu kupanga polyhedra osiyana pepala akuda, zitsanzo izi zingagwiritsidwe ntchito ngati zinthu zokongoletsera zokongoletsera nyumba - chipinda ana, ofesi, pabalaza. Mwa njira, polyhedra angatchedwe anapezazo zokongoletsera wapadera. zipangizo zamakono choti zochokera akalumikidzidwa zojambula kulenga mkati pachiyambi.
