Isamba sezilinganiso zama-engeli angaphakathi kanxantathu...
Impendulo ithi: XNUMX°.
Isamba sama-engeli kanxantathu singenye yezakhiwo ezibalulekile zezibalo zejometri okufanele zicatshangelwe.
Ubufakazi bubonisa ukuthi isamba sama-engeli kanxantathu sihlale silingana namadigri angu-180, kungakhathaliseki ukuthi unxantathu uno-engeli kwesokudla, o-acute-engeli, noma ogobile.
Kuyaziwa ukuthi ama-engeli amabili angakwesokudla kunxantathu angeza ama-degree angu-90, ngakho ubukhulu be-engeli yesithathu bungabalwa ngendlela eyodwa.
Ngaphezu kwalokho, ukuma kukanxantathu kungashintshwa ngokuhudula ama-vertices noma izinhlangothi zawo, futhi isisekelo sawo sisazoba ukuthi isamba sama-engeli awo angama-degree angu-180.
Lobu bufakazi bubaluleke kakhulu emikhakheni eminingi, njengokwakhiwa kwezakhiwo, ukwakhiwa, ukudweba kanye nobunjiniyela bemishini, futhi busetshenziswa ezinhlelweni eziningi ezisebenzayo ezingeni lomphakathi.
