Empilweni yesimanje, kwesinye isikhathi wonke umuntu kufanele athole indawo yesakhiwo, ifulethi noma igumbi. Futhi kanjani ukubala indawo? Kubukeka sengathi yonke into ilula: sithatha izinto zokulinganisa, sikala, bese kuba lapho. Cha, ngeke. Ukwenza lokhu kahle ngeke kusize izilinganiso kuphela, kodwa futhi nemisindo ebaluleke kakhulu.
Isilinganiso
Ekubaleni indawo, okokuqala, izilinganiso zensimu zibalulekile. Lesi isiqalo esifanele esizokhiqiza imiphumela. Umphumela kufanele ube unembe, ngakho-ke, kuzodingeka ukukala ngokufanele, ngephutha elincane noma ngaphandle kwalo ngokuphelele. Okokukala uzodinga:
- ukulungisa i-tepi;
- ipeni;
- ipensela;
- incwajana noma incwajana;
- umbusi omude (imitha);
- umshini wokubala.
I-Roulette ngaphandle kwe-clamp izoletha ubulukhuni obengeziwe. Musa ukusebenzisa iphepha uma ubhala kakhulu. Bajwayele ukulahleka. Ngakho-ke, kungcono uma ubhala konke phansi kubhukwana elilodwa noma incwajana.
Akudingekile ukukala eceleni kwamabhodi ezisekelo. Kwanele ukuthola ubude bodonga, futhi lokhu kungenziwa noma yikuphi, ngokwesibonelo, uma ifenisha isendleleni. Ungalinganisa ephansi, ngaphezulu, phakathi. Into esemqoka iyafana nophahla naphansi. Uma kuzoba nzima wedwa, bese ushayela umuntu ozokusiza kangcono.
Bheka ukufana okuqinile, ngokomqondo, ngemithambeka yombusi, awukwazi ukukala kunoma yikuphi. Bukela lokhu, ngaphandle kwalokho imiphumela izoba engalungile!
Amakamelo ngaphandle kwama-protrusion kuzoba lula ukukala. Ngama-protrusions ayinkimbinkimbi ngokwengeziwe: kufanele uhlukanise igumbi libe izibalo eziningana. Bala indawo ngayinye yazo, bese uyengeza. Kaningi kwenzeka.
Ubude bodonga bungasohlangothini lwesibalo. Abanye abantu bacabanga ukuthi konke kudinga ukulinganiswa: ubude, ukuphakama nokunye. Cha, lapho sithola indawo yekamelo, sibala kuphela phansi. Indawo yekamelo indawo yephansi futhi akukho okunye.
Ukubalwa kwendawo
Amakamelo ahlukile ngesimo sephansi. Yile mehluko ohlulelwa: isibalo esifanele noma esingalungile. Ngisho nomugqa omncane womnyango wenza isibalo sigcine.
Indawo ilinganiswa ngamamitha skwele. Ukubala imitha yesikwele, udinga ukwanda ngamamitha ayi-1 ngemitha eli-1.
Indawo yekamelo iyimo efanele
Ake sithi phansi kwegumbi lakho kunokwakheka okulungile: unxande noma isikwele. Ukala ngobude bazo zonke izinhlangothi ngokubhala imiphumela kubhukwana. Manje usungaqala ukubala. Bheka indawo eyisikwele ngefomula: uhlangothi luphindaphindwa ngohlangothi. Ifomula yendawo engunxande: phindaphinda uhlangothi oluncane ngobukhulu.
Noma ngabe ubona ukuthi igumbi lakho lisesimweni sikwere noma isikwele, bese ulinganisa zonke izinhlangothi, hhayi ezimbili zazo! Kungazelelwe kube nokuphambuka? Lokhu kwenzeka kaningi lapho, kubonakala sengathi, sikwele, kepha izinhlangothi zisahlukile ngobude. Lokhu kungenxa yamaphutha wokwakha.
Ngakho-ke, ukubala indawo yegumbi lesimo esifanele, udinga ukusebenzisa indawo noma amafomula wesikwele. Isibonelo, unohlangothi olulodwa olingana namamitha amahlanu, njengabo bonke abanye. Izikhathi ezi-5 bese uthola amamitha angama-25 skwele. Noma, eyodwa - 5, nenye - 8. Indawo izoba ngamamitha angama-40.
Sisebenzisa amadivaysi smart ukubala indawo - ividiyo
Lapho igumbi selakhiwe ngokungakhethi
Ezimweni ezivame kakhulu kwenzeka ngaleyondlela. Njengoba sekushiwo, noma ngabe kukhona umkhondo omncane egumbini, khona-ke awujwayelekile ngesimo. Bheka lokhu ngaphambi kokuphetha ngokunemba. Isibonelo, igumbi lakho linxantathu, kepha kukhona imikhondo. Ezimweni ezinjalo, akufanele ufune amafomula ezinombolo eziyinkimbinkimbi ukuthola indawo. Kwanele ukuhlukanisa igumbi libe izicucu, yilokho kuphela. Funa indawo yoxande, bese ulinganisa indawo yamaphrotheni bese ubala ngokwahlukana.
Isikhathi esiningi, ama-protrusion ayizindawo eziphambi kwemikhondlo ezinobukhulu boxande noma trapezoid ohlukile. Uma i-trapezoid, lapho-ke siphindaphindeka uhhafu wesamba sezisekelo ezimbili (u-A no-B) ngokuphakama (H). Yini lapho - kukhonjisiwe esithombeni. Ngokwehlukana, sibheka indawo engunxande, indawo ye-protrusion, bese sengeza lezi zindawo ezimbili. Ngakho-ke ungakwazi ukubala amamitha skwere wegumbi lilonke.
Kepha kuthiwani uma ukuphuma kungengasilo gumbi, kodwa kungene kukho? Lapho-ke kuyadingeka ukuthi ucabangele indawo yefomu elifanele, i-ledge imane idonswe phansi. Kuboniswe esithombeni. Okusho ukuthi, sifuna indawo yoxande olukhulu (esithombeni izinhlangothi zimakwe zibomvu), lapho-ke sithola indawo lapho kungenzeka khona, kanye nezindonga, bese siyisusa endaweni yelena.
Kunamakamelo angabizwa ngokuphepha ngokuthi acatshangelwe ama-multi-figured. Lokhu, ngokwesibonelo, lapho igumbi linesimo se-polygon ethile. Kufanele ujuluka lapha. Siphatha umbusi omude nepensela. Kuyadingeka ukuzama ukuhlukanisa igumbi lonke libe izibalo ezifanele, ucabangele indawo yabo futhi uyihlanganise. Ngepensela, phawula imingcele enemibandela yezibalo. Maka amaphuzu ngepensela phansi.
Amakamelo wokuqamba awasakwazi ukuhlukaniswa ngamanani afanele. Imvamisa kuhlangana nokuhlangana kwemisipha. Ungakwazi ukubala amamitha skwere wekamelo elinalolu hlobo. Ifomula yendawo ye-semicircle izosiza. Ifundeka ngalendlela: imisakazo iphindaphindwe ngenombolo pi (3.14), iphindwe kabili, ihlukaniswe kabili. Sitfombe sikhombisa luhlaka lwephansi. Ibanga ukusuka ku-A kuye ku-B ububanzi bokwengeza. Kusuka ku-A kuye ku-O umsakazo. Irediyamu iyisigamu sedayidi. Indawo ye-semicircle yengezwe endaweni yoxande.
Kunzima ngokwengeziwe uma esikhundleni se-semicircle kukhona ingxenye yayo kuphela. Ukulandelana kokubala indawo ephelele kuzohlala kunjalo. Kepha ngenxa yengxenye kufanele udle ngamakhona. Kunzima, kepha kuyaqondakala. Ngaphezu kwamathuluzi angenhla uzodinga:
- intambo eqinile;
- protractor kasayizi ophakathi;
- angajulile.
Sithatha intambo bese sibopha ushoko kuyo. Silungisa enye ingxenye yentambo ibe phansi bese sizama ukudweba odongeni oluyi-arcuate ukuze intambo ilule. Sizama ukuqeda ukuya embuthanweni noma kusihlwa. Ngakho-ke sithola isikhungo nerediyo. Lapho usuqedile, dweba ushoko.
Ngaphambi kokushayela nge-chalk, qiniseka ukuthi iphumula maphakathi ne-arc.
Ukusuka enkabeni sidonsa imigqa emibili iye emaphethelweni e-arc. Sithatha i-protractor bese silungisa i-angle phakathi kwabo. Ikusiza ukubala wokubala wemitha skwele online. Kungcono ngoba ifomula iyinkimbinkimbi.
Konke, indawo yengxenye yatholakala. Manje ungangeza indawo yayo kanye nendawo yonke yekamelo.
Indawo ephelele
Lapho izindawo zazo zonke izakhiwo zitholakala, kuzokwazi ukubala amamitha skwele kuyo yonke indlu noma efulethini. Vele ufake zonke izindawo zamakamelo. Ngakho-ke indawo ephelele iyophuma.
