Iindile eziqhelekileyo nezikufutshane

IJyometri yenzululwazi echanekileyo. Ivelisa ingcamango, ingcinga kunye nokuqonda. Ngokuqinisekileyo, ngenxa yobunzima bayo kunye nenani elikhulu leempahla kunye neengxowankulu, akusoloko imnandi kubafundi besikolo. Ukongezelela, kukho imfuneko yokuqinisekisa rhoqo ukufumana iziphumo, usebenzisa imigangatho nemimiselo eyamkelekileyo.

Iibangele ezisezantsi kunye neengcingo ziyingxenye ebalulekileyo yejometri. Ngokuqinisekileyo abaninzi abantwana besikolo banamathela nje ngenxa yokuba iimpahla zabo zicacile kwaye zilula kubungqina.

Ukuqulunqwa kweenglesa

Naliphi na i-angle ikhiwa ngokuwela imigca emibini echanekileyo okanye ukubamba iiplanga ezimbini ukusuka kwindawo enye. Baya kuthiwa yileta enye okanye ezintathu, ezibonisa ngokuqhubekayo amaphuzu ekwakhiweni kwekota.

Iibhilo zilinganiswa ngamadireji kwaye zinako (kuxhomekeke kwixabiso) zibizwa ngokuba zihlukile. Ngoko, kukho ikona elungileyo, elibukhali, elibi kwaye libonakala. Kulo ngalinye la magama apho lihambelana nomlinganiselo othile okanye ikhefu layo.

I-angle ephilileyo ibizwa ngokuba yimilinganiselo engadluli kuma-degrees angama-90.

I-angle engacacanga ikhulu kunama-90 degrees.

I-angle ibizwa ngokufanelekileyo ukuba umlinganiselo we-degree is 90.

Kwimeko xa ibunjwa ngumgca omnye oqhubekayo, kwaye umlinganiselo we-degree u-180, ubizwa ngokuba wandisa.

Iintsimbi ezijonge

Ama-Angle anesiqhelo esifanayo, kwicala lesibini eliqhubela phambili, libizwa ngokuba liseduze. Zingaba zibukhali okanye ziyatha. I-intersection yekhonkco evelele ngeefom zelayini ezikufutshane. Iipropati zabo zilandelayo:

1. Isibalo sama-angles anjalo siya kuba ngama-180 degrees (kukho imfundiso ebonisa le nto). Ngoko ke umntu unokubala ngokulula omnye wabo ukuba omnye uyaziwa.
2. Ukususela kumgca wokuqala ulandela ukuba iibangele ezikufutshane azikwazi ukubunjwa ngamacangca amabini okanye ama-angles acute.

Ngenxa yezi mpawu, unako ukubala isiqingatha somlinganiselo we-angle, enexabiso lentsimbi enye okanye, ubuncinane, ubudlelwane phakathi kwabo.

Amangles aphilileyo

Ama-Angles, amacala ayo aqhubekayo, abizwa ngokuba ngama-angle angles. Njengokuba loo mbini inokuyenza nayiphi na imihlobo yazo. Ama-angles aphilileyo ahlala elingana nomnye.

Ziyakhiwa xa imigca ihamba. Kukho kunye nabo behlala bekhona. Ikhonkco inokubakho ngexesha elifutshane kunye nelinye nelinye.

Xa udibanisa imigca efana nomgca ongathandabuzekiyo, ezinye iindidi zee-angles nazo ziqwalaselwa. Umgca onjalo ubizwa ngokuba ngumgca wecala, kwaye ufana neefowuni ezihambelana nendawo kunye nomgca. Ziyalingana. Ziyakucingelwa ngokukhanya kweempawu ezinama-angles angama-vertical and adjacent angles.

Ngaloo ndlela, umxholo weenglesa ubonakala ulula kwaye uqondakala. Zonke iipropati zabo zilula ukukhumbula kwaye zibonakalise. Ukuxazulula iingxaki azibonakali nzima kunokuba iikona zihambelana nenani lamanani. Sekudlulileyo, xa kuqhutyelwa isifundo sesono ne-cos, kuyakufuneka ukuba ikhumbule ezininzi iifomula eziyinkimbinkimbi, izigqibo zabo nemiphumo. Kuze kube ngulo xesha, unokonwabela imisebenzi elula apho kuyimfuneko ukufumana ama-angles ajikelezayo.
