Ake sifunde ndawonye ngensimbi engela.

Ukuhlukaniswa kwensimbi ye-engela: Insimbi ye-engela ngokuvamile ihlukaniswa ngensimbi ye-engela enezinhlangothi ezilinganayo kanye nensimbi ye-engela enezinhlangothi ezingalingani ngokusekelwe kubukhulu bezinhlangothi zayo ezimbili.

I. Insimbi ekhoneni elilinganayo: Insimbi ekhoneni enezinhlangothi ezimbili zobude obufanayo.

II. Insimbi engela ohlangothini olungalingani: Insimbi engela enezinhlangothi ezimbili ezinobude obuhlukene.
