I-Calculator ye-Triangle
Kuxazululwe noma yisiphi isithathu kusuka ezinyaweni nakuma-angles - indawo, umkhawulo kanye nama-values angekho.
Ngeza noma yiziphi izimali eziyi-3 (ingxenye eyodwa noma ngaphezulu). Izingxenye a, b, c ziyi-angles eziphikisanayo A, B, C.
Faka amaxabiso amathathu ukuxazulula.

Imibuzo ebuzwa kaningi
Yini okufanele ngiyazi ukuze ngixazulule i-triangle?
Nanoma yiziphi izindleko ezintathu ezifaka ikhasi elilodwa: amakhasi amathathu (SSS), amakhasi amabili ne-angle efakwe (SAS), ama-angles amabili nekhasi (ASA/AAS), noma amakhasi amabili ne-angle engafakwanga (SSA).
Indlela ekhokhwa ngayo indawo?
Kusuka ezinhlangothini ezintathu isebenzisa ifomula kaHeron; ngezinhlangothi ezimbili ne-angle efakwe isebenzisa ½·a·b·sin(C). Zonke zinikeza imiphumela efanayo ye-triangle esebenzayo.
Ngizoxazulula kanjani i-3-4-5 triangle?
Ngeza amaphesenti amathathu njenge-3, 4 ne-5 bese ushiya ama-angles amnyama. I-calculator iqinisekisile ukuthi iyi-triangle eqondile ene-angle engu-90° ephikisana nengxenye ye-length 5, ama-angles angaphezu kuka-36.87° ne-53.13°, indawo engu-6 ne-perimeter engu-12.
Yini ushintsho phakathi komthetho we-sines nomthetho we-cosines?
Umthetho we-cosines uxhuma zonke izinhlangothi ezintathu ku-angle eyodwa, ngakho kusetshenziswa uma ungazi izinhlangothi ezintathu noma izinhlangothi ezimbili ne-angle efakwe. Umthetho we-sines uxhuma inhlangothi ku-angle ephikisana nayo futhi kusetshenziswa uma unengxenye elinganayo ye-angle.
Kungani i-SSA ngamanye amaxesha inikeza ama-triangles amabili akhona?
Ngezingxenye ezimbili ne-angle engafakiwe (isibonelo esicacile), ingxenye enikezwe ingafinyelela isizinda ezingeni ezimbili ezahlukene, ngakho-ke ama-triangles amabili afanele angafaka idatha efanayo. I-calculator ikhombisa lokhu uma kwenzeka.
Ingaba ingamitshela uma amaxabiso ami angeke ahlanganise isithathu esifanele?
Yebo. Uma amapheya ephula ukungalingani kwe-triangle (ipheya elinye lide kunamanye amaphiko amabili axhunywe) noma ama-angles angaba yi-180°, i-calculator ikhombisa ukuthi akukho lutho olunjalo olufana ne-triangle endaweni yokubuyisela imiphumela.
Izibalo ziyisilinganiso esisetshenziswa ukuqondisa kuphela, hhayi ukucebisa ngezimali, ukwelashwa noma ukukhokha.
