Piramidi - Kujambula. Aone piramidi kulumikiza. pepala jambulani

Rectangle, lalikulu, makona, trapezoid ndi ena - akalumikidzidwa zojambula pa chigawo cha sayansi yeniyeni. Piramidi - ndi polyhedron. Maziko a chithunzi ichi ndi polygon, ndi mbali nkhope Triangles kukhala vertex wamba, kapena trapezoid. zitsanzo anapangidwa kuti limvetse mokwanila kuphunzira ndi chinthu chilichonse zojambula. Iwo amagwiritsa ntchito nkhani zambiri zosiyanasiyana imene muli piramidi. Pamwamba pa chithunzi Mipikisano faceted, kufalitsidwa mu ndege, lotchedwa jambulani ake. Pangani njira Kamangidwe chingatithandize kusintha zinthu mosabisa mu polyhedrons atatu azithunzi omwe tikunena ndi ena odziwa Masamu. Chindodo wa pepala kapena makatoni n'kovuta kupanga. Luso chofunika kuchita zojambula za kukula kwake achikhalire.

Katundu ndi Chalk

Mawerengeredwe ndi kukhazikitsa m'zigawozigawo buku mosiyanasiyana zojambula - ndondomeko chidwi kwambiri. Paper zikhoza kupangidwa ambiri masanjidwe zosiyanasiyana. Ntchito zidzafunika:

• pepala kapena paperboard;
• lumo;
• pensulo;
• mzere;
• Zimalondolera;
• erasers;
• ulimbo.

KUFOTOKOZERA magawo

Choyamba umakhala kodi piramidi. Jambulani chithunzi ichi ndicho chiyambi cha ulimi wa mawonekedwe chochuluka. Pitani ku ntchito Zidzatengera mogometsa kwambiri. Pa chojambula cholakwika chithunzi zojambula kadzakulakani kusonkhanitsa. Yerekezerani kuti mukufuna kupanga kamangidwe wa nthawi zonse triangular piramidi.

Aliyense thupi zojambula ali katundu wina. chithunzi Izi m'munsi zonse polygon, ndipo nsonga yake ntchito mu malo ake. Monga m'munsi pa amusankha equilateral makona. Makonzedwe amenewa n'chakuti dzina. mbali ndi mbali pa piramidi - kansalu, amene chiwerengero zimadalira anasankha polyhedron m'munsi. Pankhaniyi, padzakhala atatu. M'pofunikanso kudziwa kutalika kwa zigawo zonse, zimene piramidi adzakhala wasenza. Chindodo pepala akutsatiridwa mogwirizana ndi deta zonse zojambula mawonekedwe. Magawo a tsogolo chitsanzo mwachindunji pasadakhale. Pazimene izi, kusankha zimadalira kugwiritsidwa ntchito.

Kodi Ine aone piramidi zonse?

Chifukwa cha chitsanzo ndi pepala kapena makatoni. ntchito akuyamba ndi zojambula za piramidi. Chithunzi akuimira mu mawonekedwe kukodzedwa. Pamwamba fano pepala Chofanana mbali preselected ndi magawo. Zonse piramidi ali m'munsi mwa polygon zonse, ndi kutalika kwa umadutsa pakatikati ake. Ifenso chitsanzo wosavuta poyambira. Pankhaniyi - ndi triangular piramidi. Kudziwa kukula kwa mawonekedwe owerengeka. Kumanga mapiramidi jambulani amene m'munsi ndi makona equilateral, likulu la pepala, pogwiritsa mkulu ndi cholembera jambulani anapatsidwa m'munsi kukula. Pafupi mbali limachokera ndi nkhope mbali ya piramidi - Triangles. Tsopano ife tikupita ku yomanga awo. Makulidwe mbali pamwamba mbali ya Triangles ndi kuyeza Zimalondolera. Mwendo wa kampasi mu pamwamba m'munsi penti ndi kupanga mphako. Action kubwereza, kusamukira ku mfundo ina ya makona lapansi. The mphambano chifukwa zimenezi, nkhope mbali chimatanthauza mfundo za piramidi. Iwo alumikizana ndi patsinde pa. Mafanizo kupeza piramidi. Kulumikiza akalumikidzidwa volumetric pa mbali lateral nkhope kupereka mavavu. Dorisovyvat trapezoid yaing'ono.

Kamangidwe msonkhano

Kudula ndi lumo zopangidwa mizere kujambula. Pang'ono pang'ono unakhota aone pa mizere onse. Mavavu ovala ndi trapezoid mawonekedwe mkati kotero kuti nkhope yake kutsekedwa. Iwo mafuta guluu. Mphindi makumi atatu pambuyo pake, zomatira uphwetsa. Volume zili wokonzeka.

Jambulani quadrangular piramidi

Choyamba, talingalirani zomwe zikuwoneka ngati chithunzi zojambula, kamangidwe amene adzakhala chopangidwa. Base amusankha quadrangle piramidi. Mbali nthiti - Triangles. Ntchito pogwiritsa ntchito zipangizo zofanana ndi zipangizo, monga Baibulo m'mbuyomu. chojambula chikachitika pa pepala ndi pensulo. Pakati pa pepala ndi kujambula rectangle ndi magawo anasankha.

Mbali ya kugawikana m'munsi mwa theka. Lembani perpendicular, amene adzakhala pamwamba pa nkhope triangular. Anakonza Zimalondolera kutalika wofanana nkhope mbali ya piramidi, kuti perpendiculars serifs, atakhala maziko ake mwendo pamwamba. Onse mbali ya mbali imodzi ya m'munsi ndi kulumikiza mfundo analandira pa perpendicular. Chifukwa ndi pakati pa kujambula lalikulu, pa nkhope utoto Triangles. Kukonza chitsanzo pa zipupa zam'mbali dorisovyvayut mavavu wothandiza. Kuti mokwanira odalirika yolusa n'kupanga centimeter m'lifupi. Piramidi ndi wokonzeka msonkhano.

Chomaliza kukhazikitsa mawonekedwe a

Chifukwa podula zidutswa chitsanzo pamodzi mizere ya. Usilikali pa mizere kukhotetsa pepala. Chiwerengerochi Collection buku umatulutsa gluing. Mavavu anapereka lubricates zomatira ndi kukonza chitsanzo chifukwa.

zitsanzo Volumetric mosiyanasiyana zovuta

Atam'chiritsa ndi zitsanzo yosavuta polyhedron angachititse kuti akalumikidzidwa zovuta kwambiri zojambula. Jambulani truncated piramidi ndi ovuta kwambiri mu kuphedwa. zapansi ake ofanana polyhedra. mbali nkhope - ndi trapezoid. The ndondomeko ya ntchito zidzakhala chimodzimodzi ndi yemwe zomwe zimachititsa piramidi yosavuta. Jambulani adzakhala wolemera. Kuchita zojambula ntchito pensulo, wolamulira ndi kampasi.

Kumanga zojambula

Jambulani truncated piramidi zachitika mu magawo angapo. Mbali nkhope ya piramidi truncated ndi trapezoid ndi zapansi - ngati polyhedra. Tiyerekeze lalikulu ili. Pa pepala trapezoid kuchita kujambula ndi miyeso yake. mbali ya kanjedza chifukwa ali yaitaliyo dalaivala. The chifukwa ndi isosceles makona. mbali Yake ya Zimalondolera kuyeza. Pa pepala mapepala, ife kumanga bwalo ndi utali wozungulira umene uli patali anayeza.

Siteji yotsatira - yomanga m'mbali lateral, umene ndi truncated piramidi. Jambulani imagwiridwa mwa bwalo kukopedwa. Kuyeza Zimalondolera m'munsi m'munsi mwa trapezoid ndi. Tingaonenso pa bwalo mfundo zisanu zomwe ogwirizana ndi pakati mzere wake. Tili anayi Triangles equilateral. Kampasi muyeso wa trapezoid ndi limachokera pa pepala osiyana. Mtunda Izi kulepheletsa kukopedwa pa mbali Triangles lapansi. Mfundo analandira ogwirizana. The mbali nkhope ya trapezoid ndi okonzeka. Iwo okha mpaka jambulani chapamwamba ndipo m'munsi m'munsi mwa piramidi. Pankhaniyi, polyhedra awa - mabwalo. Chapamwamba ndipo m'munsi m'munsi mwa choyamba mabwalo trapezium dorisovyvat. The chojambula limasonyeza m'madera onse amene ali piramidi. Jambulani ndi pang'ono. Iwo okha mpaka kumaliza mavavu lumikiza pa mbali ya lalikulu ndi kocheperako wa nkhope ya trapezium lapansi.

Akamaliza mawerengeredwe

Pamaso gluing volumetric chithunzi Chithunzi cha mizere kudula ndi lumo. Kenako, jambulani mosamala apangidwe motsatira mizere usilikali. Akukonzekera mavavu refueled mkati chitsanzo. mafuta awo zomatira ndi unkagunda m'mbali mwa piramidi. Chitsanzo kupereka youma.

Kupanga zitsanzo zosiyanasiyana za polyhedra

Kuchita zitsanzo volumetric mosiyanasiyana zojambula - chokuchitikirani zosangalatsa. Kuphunzira bwino, muyenera kuyamba ndi kukhazikitsa wa mapanga sikani zophweka kwambiri. Pang'onopang'ono amayenda zamanja yosavuta zitsanzo zina, inu mukhoza kulenga kapangidwe kwambiri zosamvetsetseka.
