Kubatsira vechiduku nemhizha sei kuti pepa kubva tetrahedron

Kana pakarepo iwe vakapiwa basa iri geometry chidzidzo, kana pacharwo chido vasimbise ndangariro ehupfumi ose-dimensional matatu dzemitambo, unofanira zvechokwadi. kuverenga sei kuti pepa kubva tetrahedron, uye kuva nechokwadi kuti kushandisa mazano aya kupinda tsika. Pashure pezvose, mufananidzo uyu nokuda kwayo nyore ndechimwe inokosha yemashoko-dimensional matatu Modelling.

Shoko "tetrahedron" anogona kushandurwa kubva muchiGiriki se "tetrahedron". Zvechokwadi, chinangwa chiri mubvunzo ine mana mativi zviso zvina vertices matanhatu micheto. Kune subspecies wandei nhamba iyi, asi isu hatingazvirumbidzi kukurukura zvose zvinobvira kuita. Munyaya ino uchadzidza nezvenzira sei kuti pepa tetrahedron. Izvi zvichava nguva tetrahedron, vose vane zviso vari equilateral zvokuridza.

Nokuti basa havafaniri kupinda kunzwisisa masvomhu havafaniri kuverenga chero vhoriyamu imwe tetrahedron, kana imwe nzvimbo kana kukwirira. Chinhu bedzi kunodiwa, - papepa, penzura, chigero uye guruu, uye SRES uye anogona kuita chete nepepa.

Sezvo bepa kuti tetrahedron, yose anodiwa zvinhu? Pane nzira dzakawanda. Wekutanga dzakakurumbira zvikuru maonero: akagura mana vakaparadzana zvokuridza pamwe vainzi "petals", ayo zvino glued pamwechete. Unogona kuswedera ane equilateral netriangle pamusoro dzavo kana kushandisa makagadzirira akagadzirwa templates. Zvakanakira nzira iyi anosanganisira mukana kuumba munhu multi-mavara, achitora mapepa mavara akasiyana uye maketeni. Nyaya ino ndichapa richipenya uye kunakidza Kutarira.

A nzira yechipiri ine mu chokuedza kwete kuparadzanisa zvokuridza, uye kare chokuita mumwe (anonzi kushanda pakuvheneka tetrahedron). Muchiitiko chino, zvakare, pangava zvokusarudza anoverengeka, kureva kuti gluing ari petals angava zvose rakazaruka micheto, kana chete vamwe, vaya vane kwenguva yakachengeteka ukamubvundisa.

Uye pakupedzisira, nzira vakatarisa sei kuti pepa kubva tetrahedron yechitatu, tinogona kuona kuti hapana chikonzero kunyange chero adhesives, nekuti mumwe pachake paungano geometric hakusi modular Kurumi. Heunoi mukaha Pyramid anogona kuitwa nokushandisa nzira iyi, pamwe kudanda yakakwana mapepa, kutsungirira uye kushivirira. Kazhinji, hazvina kunzwisisa chaizvo, asi rakaoma basa, uye munyaya ino hatingavapi mirayiridzo hwakadzama. Kana uchifarira ruzivo urwu, uchaona zviri muna zvinyorwa Rakakwanira muri ichi Japanese. Uye, kana iwe ukaita kupa dambudziko kuwana mirayiridzo iyi rwokugadzira, nokukurumidza uchawana nyore kunyange kunzwisisa maumbirwo yakadaro.

Mumwe nomumwe pamusoro nzira ine zvakwakanakira pamusoro vamwe, uye vose vakakodzera uye inobudirira. Uye sarudza nzira kuti zvakakunakira inofanira kuvakirwa Kuwanikwa nguva uye kushivirira, uyewo chinangwa muenzaniso Remangwana tetrahedron.
