Kuqondile nama-engeli eduze

Jiyomethri - lena isayensi kakhulu yehlukene kaningi okubalwa. Kutfutfukisa logic, umcabango kanye nezobunhloli. Yiqiniso, ngenxa yinkimbinkimbi yayo kanye nenani elikhulu theorems futhi axioms, akusiyo njalo like besikole. Ngaphezu kwalokho, kukhona isidingo njalo ukufakazela lokho abakutholile, usebenzisa amazinga ajwayelekile kanye nemithetho.

engeli eduze futhi mpo - kuyinto ebalulekile ingxenye geometry. Ngineqiniso abafundi abaningi nje uyabathanda ngenxa yokuthi izakhiwo zabo zicacile futhi kulula ukufakazela.

emakhoneni Ezemfundo

Noma yimuphi engela ezakhiwe empambana imigqa emibili noma imishayo amabili beqhuba kusukela iphuzu elilodwa. Zingase ngokuthi noma incwadi eyodwa noma ezintathu, okuyinto ngokulandelana esiqokiwe iphuzu yokwakha ekhoneni.

Angles kulinganiswa ngokwamazinga, futhi kungaba (kuncike value abo) ehlukile okuthiwa. Ngakho, kukhona engela kwesokudla, i-acute, obtuse futhi ukhiphe. Ngamunye amagama oluhambisana ngezinga elithile noma isilinganiso esithile span yayo.

Ngokuthi engela oyingozi, isilinganiso okuyinto ingeqi 90 degrees.

Kuyinto engela obtuse mkhulu kunezinhliziyo 90 degrees.

Engela okuthiwa oqondile esimweni uma 90 degree ngesilinganiso.

Esimeni lapho kubunjwa khona it is a line olulodwa okuqhubekayo, futhi degree yayo ngesilinganiso ilingana 180, ibizwa ngokuthi zenzeka.

engeli eduze

Angles kokuba side ovamile, nasohlangothini lwesibili okuyinto uyaqhubeka omunye komunye ngokuthi eduze. Zingaba kokubili abukhali futhi blunt. Empambana ngqo engela umugqa yakha emakhoneni ohlanganisa. izakhiwo zabo zimi kanje:

1. Isamba yalezi engeli kulingana 180 degrees (kukhona theorem ekufakazisa). Ngakho-ke, thina kalula ukubala omunye wabo, uma wazi ezinye.
2. Kusukela esigabeni sokuqala ukuthi emakhoneni eduze zingase zimiswe by engeli amabili blunt noma ezimbili oyingozi.

Ngenxa yalezi izakhiwo, kuba njalo kungenzeka ukubala ukulinganiselwa kwe-engeli-degree athile, ukuba ukubaluleka omunye engela noma, okungenani, lihlela isilinganiso phakathi kwama kubo.

engeli mpo

Emakhoneni, izinhlangothi zazo izandiso nomunye abizwa ngokuthi mpo. Ngenxa yalokho i-pair angenza noma yimuphi izinhlobo zawo. engeli Kuqondile zihlale ulingana nomunye.

Basuke kwakhiwa ezimpambanweni zomgwaqo emigqeni. Ndawonye nabo zihlale engeli samanje futhi eduze. I-engeli kungenzeka ngesikhathi esisodwa eduze komunye nomunye futhi mpo.

Ezimpambanweni zomgwaqo imigqa parallel i umugqa ngokungenasizathu nawo acabangela izinhlobo eziningana engeli. Lo mugqa libizwa Imi, futhi lwakha abafanele sohlangothi olulodwa futhi engu- amanga engeli. Bayalingana. Abakwazi ukubona ukukhanya izakhiwo, okuyizinto engeli amile eduze.

Ngakho, i-engeli isihloko ulula futhi icacile. Zonke izakhiwo zabo kulula ukukhumbula futhi ukufakazela. Tinkinga tetibalo akunzima nje engele uhambelana inani lenombolo. Usuvele lapho kufanele ziqale isifundo wesono cos, kufanele sikhumbule amafomula ayinkimbinkimbi amaningi, iziphetho zabo nemiphumela. Kuze kube yileso sikhathi, ungakwazi nje ujabulele puzzle ukukhanya, okuyinto kudingeka uthole emakhoneni eduze.
