Kanjani ukufunda izibalo zama-engela kanye protractor ukuphrinta?

Jiyomethri njenganoma yikuphi isayensi ngqo, akakubekezeleli self ukunganakwa. Futhi ukumsiza ukufunda izisekelo, izingane kufanele uchithe imfuno elincane ngenalithi. main theme lakhe okulandelayo: indlela yokwenza protractor. Lokhu kuzodinga kancane: sikelo, iglu, iphepha A4, amakhadibhodi obukhulu, amakhrayoni, izimpawu, upende, emabhulashini, decor ezahlukene, iphrinta, kahle, lapho ukwenza ngaphandle a ton of ukubekezela nokuphefumlelwa isikhwama! Isidingo ukwenza lo msebenzi ngaphambi yengane phikisana ukuntuleka onjalo gauge ebalulekile engeli esitolo noma ukuze sikhuthaze izindlela zalo ezingaphezu evamile ngawe.

preliminaries

Into yokuqala ukuthi ziyokuwa ngokuphelele emahlombe akho kuyoba ukulungiselela isifanekiso. Ngaleso sikhathi samanje ukuthola kukho efanelekayo akunzima. Uma ungumnikazi umhleli ihluzo, ungakha indlela eyingqayizivele engafaniswa nesithombe sakho umndeni, amagama, izinhlamvu opopayi ozithandayo. Kodwa abayi wathumba, ngoba indlela uzothola anemibala iphepha protractor - ukuphrinta, futhi ngokuhlanganyela yokuzilibazisa isikhathi izakhi ukuqeqeshwa ngeke iphazamiseke.

A ikhambi elingcono kakhulu kungaba ukuqeqeshwa kuphela wesifunda nge esikalini digital okuzokwenziwa zaveza futhi ngcono ngenye indlela. Futhi kubalulekile ukuba sithole ukuze ukunyathelisa protractor - round for lula ukubonisa, umkhumbi ne amanani asuka degrees 0 kuya ku-180. Uma izindlela ezilula ezinjalo azibona ngawe, vele uye isethulo yezindlela endaweni trigonometry okunengqondo.

Patrimony futhi okuncane mayelana okwamanje

Ngaphambi isinqumo esiwujuqu mayelana hlobo luni protractor ukuphrinta, ungakwazi ukutshela ingane yakho ngokufunda umlando lo mshini (esebuyile eBabiloni lasendulo), ukwethula sexagesimal simiso ukubala kanye imiqondo yayo eziyisisekelo - degrees, imizuzu, imizuzwana. Ungabi kahle uthinte ku izimpikiswano engeli isicelo emphakathini wanamuhla, e geodesy futhi ekudwetshweni kwamabalazwe, isakhiwo, ubunjiniyela, njll, bonisa izinhlobo ezinkulu emakhoneni -. Olunamandla, obtuse, iqonde, ongaqaqiwe, abuye achaze umehluko phakathi kwabo. Kunconywa ukubonisa lezi ukunikela emakhoneni zabo ukwakha on ngesisekelo kwabo imidwebo ngezinto ezihlukahlukene. Nakuba-ke ngeke kwenziwe ukuhlola indlela protractor ukuphrinta: kuyadingeka ukuze uthole ukuthi iqondeni njengesibonisi ayilungiselele kusengaphambili, futhi isinqumo salo. Umqondisi womshini Ubuye ukubonisa idatha ngaphandle warping noma ukuhlanekezela. Ungase udinge ukuhlanza noma kulungiselelwa.

kunqubo

Ngemva kokunquma onjani protractor ukuphrinta, wena nje chofoza inkinobho "Phrinta" (amakhophi amaningi), bese usika eduze imininingwane nentaba. Kufanele khombisa ukunemba, ngoba noma ikuphi ukungafani kuyoba emehlweni. Bese uqhubekela phambili umhlobiso protractor. Ngenxa yale njongo ngeke asondele lutho, inketho kuncike kuphela malini bathumba kule bhizinisi.

Zonke izinhlobo umbala ukwakhiwa, izindikimba ukotini kanye kudabuke ezahlukene imibala, uvolo, ukotini, izitika, ubuhlalu, rhinestones neminsalo uzothola ukusetshenziswa, njengoba kulokhu, ngokweqile zabo ngeke abaphumeleli. Emva kokuqeda i-protractor ukubaluleka kwezobuciko kuzokhulisa izikhathi eziningi, kungaba ethe njo ungene amakhadibhodi nokwenza imbobo iphuzu lapho nesilinganiso iqala. Naphezu kweqiniso lokuthi lesi senzakalo self-ezenziwe singaba ngaphansi elula ukusebenzisa kuka nabazala bayo ecacile prefabricated, ngeke abashiye ubani nandaba ngenxa ukubukeka amnandi futhi ukuklanywa. Leyo misebenzi ezikanye ingane uzokunika okuningi izikhathi ezimnandi esikhathini esizayo.
