Kule ncwadi, sizocubungula ukuthi siyini isilinganiso se-engeli, ukuthi ikalwa kanjani. Siphinde sinikeze isizinda somlando esifushane ngalesi sihloko.
Ukunqunywa kwesilinganiso sedigri ye-engeli
Inani lokuzungezisa ibhimu AO azungeze ichashazi O esibizwa isilinganiso se-engeli.
Isilinganiso sedigri ye-engeli – inombolo ephozithivu ebonisa ukuthi idigri kanye nezingxenye zayo (umzuzu nesekhondi) kungena kangaki kule engeli. Labo. yisamba senani lamadigri, amaminithi, namasekhondi phakathi kwezinhlangothi ze-engeli.
I-Angle - lesi sibalo sejometri, esakhiwe ngababili abavela endaweni eyodwa (i-vertex ye-angle).
I-engeli eseceleni yimisebe eyakha i-engeli.
Amayunithi e-engela
Degree – iyunithi eyisisekelo yokulinganisa ama-engeli endiza ku-geometry, elingana no-1/180 we-engeli eqondile. Kubizwa ngokuthi “°".
iminithi ingu-1/60 wedigri. Uphawu lusetshenziselwa ukuchaza'".
Okwesibili ingu-1/60 weminithi. Kubizwa ngokuthi “′′".
izibonelo:
- 32 ° 12′ 45 ″
- 16 ° 39′ 57 ″
Ithuluzi elikhethekile livame ukusetshenziswa ukukala ama-engeli - i-protractor.
Indaba emfushane
Ukukhulunywa kokuqala kwesilinganiso sedigri kutholakala eBhabhiloni Lasendulo, lapho kwasetshenziswa uhlelo lwezinombolo zobulili. Ososayensi bangaleso sikhathi bahlukanisa indilinga ibe ama-degree angu-360. Kukholakala ukuthi lokhu kwenziwa ngenxa yokuthi cishe kunezinsuku ezingama-360 onyakeni welanga, ukufuduka kweLanga nsuku zonke kanye ne-ecliptic nezinye izici nazo zacatshangelwa. Ngaphezu kwalokho, kwakulula ukwenza izibalo ezihlukahlukene.
Ijika eli-1 = 2π (ngama-radians) = 360°
