Iimpawu zokufana koonxantathu: imiqondo kunye nobubanzi

Ingqiqo ebalulekileyo kwiJometri, njengenzululwazi, ifana nemifanekiso. Ulwazi lo mpa luvumela ukuxazulula inani elikhulu lemisebenzi, kubandakanywa nobomi bokwenene.

Iingcamango

Amanani anjalo yilowo anokukwazi ukuguqulelwa komnye nomnye ngokuphindaphinda onke macala ngumbalo othile. Ama-angles ahambelanayo kufuneka alingana.

Makhe siqwalasele ngokubanzi malunga nokufana kweentantathu. Kuzonke, kukho imigaqo emithathu esivumela ukuba siqinisekise ukuba amanani anjalo analo propati.

Isibonakaliso sokuqala sokufana koonxantathu sifuna ukuba ukulingana kweebini zombini zee-angles ezihambelanayo zenzeke.

Ngokomgaqo wesibini, amanani acatshangelwayo acingelwa njengamanye amahlangothi omnye alinganayo kumacandelo ahambelana nomnye. Kule meko, ama-angles ayenziwe ngabo kufuneka alingana.

Kwaye, ekugqibeleni, isibonakaliso sesithathu: iinxantathu ziyafana ukuba onke amacandelo awo ahlukeneyo.

Kukho amanani anjalo, apho ezinye iipropati zingabalwa njengeentlobo ezikhethekileyo (i-equilateral, isosceles, i- rectangular). Ukuphikisa ukuba ezo zinxantathu ziyafana, kubalulekile ukwenza imiqathango embalwa. Ngokomzekelo, siqwalasela iimpawu zokufana kweerantangali Triangles:

1. I-hypotenuse kunye neminye yemilenze yomnye iyahlula kumacala ahambelana nomnye;
2. Naliphi na i-angle ye-acute yomfanekiso omnye ulinganayo kwenye.

Ukuba iimpawu zokufana kwee-triangles ziyabonwa, ezi ndawo zilandelayo zibambe:

1. Umyinge wezinto zawo ezingqinelanayo (abalamlamli, ama-bisectors, iindawo eziphakamileyo, ii-perimeters) zilingana ne-coefficient efanayo;
2. Ukuba sifumana umphumo wokuhlula imimandla, sifumana isikwere sale nombolo.

Isicelo

Iipropati eziqwalaselwe zivumela ukuxazulula inani elikhulu leengxaki zejometri. Ziyasetyenziswa ngokubanzi ebomini. Ukwazi imiqondiso yokufana kweentantathu, unokumisela ukuphakama kwento okanye ukubala umgama ukuya kwindawo engenakufikeleleka.

Ukuze ufumane, umzekelo, ukuphakama komthi, kumgama ochazwe ngaphambili, ipolisi isetyenziswe ngokukhawuleza, apho ibarti ejikelezayo ifakwe. Kujoliswe kwi-top yento kunye namanqaku phantsi komhlaba apho umgca oqhubekayo uya kudlula umda ophezulu. Sifumana amathantathu angama-rectangular. Ukulinganisa umgama ukusuka kwinqanaba ukuya kwisibonda, kwaye emva koko, sifumana ukulingana okulinganayo. Ukwazi ukuphakama kwesibonda, unokubala ngokulula iparamitha efanayo yomthi.

Ukufumana umgama phakathi kwamanqaku amabini kwimihlaba, sikhetha kwi-moya enye enye. Emva koko silinganisela umgama ukusuka kuwo ukuya kufumaneka. Siza kudibanisa onke amanqaku kumhlaba kwaye silinganise ama-angles angasecaleni kwesahlulo esaziwayo. Emva kokwakha unxantathu ofanayo kumaphepha kwaye uqikelele umlinganiselo wamacandelo amanani amabini, sibala ngokulula umgama phakathi kwamanqaku.

Ngaloo ndlela, iimpawu zokufana kwee-triangles zingenye yezona zinto zibaluleke kakhulu zejometri. Isetyenziswe ngokubanzi kungekhona kwinjongo yesayensi kuphela, kodwa nakweminye imfuno.
