Angle ngqo, yaba buthuntu, ezibukhali ngqo

Masiqalise ingcaciso oko ekujikeni. Okokuqala, yinto nani yemigca. Okwesibini, ukhandwa imiqadi ezimbini, ezibizwa macala-engile. Okwesithathu, nabokugqibela ngaphandle ingongoma enye, leyo ibizwa ngokuba enekona ye ekujikeni. Ngokusekelwe kwezi mpawu, singenza isigqibo: lembombo - imilo zejiyometri, equka imiqadi ezimbini (emacaleni), ukusuka kwindawo enye (phezulu) avela.

Bona zihlelwa ngokungqinelana kwixabiso isidanga, ilungiselelo ngokuphathelele omnye komnye yaye xa kuthelekiswa la manani achazwe apha. Masiqalise kunye iintlobo engile ngokobungakanani yabo.

Kukho iintlobo eziliqela. Makhe siqwalasele uhlobo ngalunye.

iintlobo ezisisiseko zabo bonke ezine iikona - ngqo, yaba buthuntu, ezibukhali engile ngqo.

ngqo

Kubonakala ngathi le nto:

iziqu zakhe kusoloko umlinganiselo ^we-90, ngamanye amazwi, ukuba esinekona sasekunene --engile degrees 90. Bakuba ke ezi quadrangles, zombini isikwere kunye noxande.

buthuntu

It has ifomu:

umlinganiselo Degree se -engile obtuse usoloko mkhulu ^kuno-90 kodwa ngaphantsi ^kwama-180. Oko kunokuthi kwenzeke ngayo quadrangles ezifana irhombus, a engenasizathu parallelogram, xa zisahlulwa.

ezibukhali

Kubonakala ngathi le nto:

umlinganiselo Degree le angle etsolo usoloko ° ngaphantsi ^kwama-90. Ifumaneka kuzo zonke quadrangles, ngaphandle isikwere kunye parallelogram ngokwesigqibo esicalanye.

ezisiwe

angle Extended yile ilandelayo:

Iimilo akwenzeki, kodwa akukho kubaluleke ngaphantsi ngaphezu kwabanye. Straight nange - imilo zejiyometri, umlinganiselo degree usoloko ulingana 180º. Kuyenzeka ukuba ukwakha kwiimbombo ezikufutshane, echitha evela ngemiqadi phezulu enye okanye ngaphezulu kuwo onke amacala.

Kukho i-engile ezimbalwa iintlobo minor. Akafundiswanga ezikolweni, kodwa yazi ubuncinane ubukho babo kuyimfuneko. iintlobo Minor iikona ezintlanu kuphela:

1. Zero

Kubonakala ngathi le nto:

kanye Igama engile sele uthetha ubukhulu bakhe. nezibilini zayo ngu 0 ^o, buxoki isandla omnye komnye njengoko kubonisiwe kulo mzobo.

2. Oblique

ROOTN kunokuba zombini ngqo yaye yaba buthuntu, engile ezibukhali tye. imeko yayo engundoqo - kufuneka ibe 'elingana ^no0 °, ^{90 °, 180} °, 270 ^°.

3. khaxa

Ingaba zero khaxa, ngqo, yaba buthuntu, iikona ezibukhali kwaye zisasazwa. Njengoko usazi, ngomlinganiselo isidanga engile khaxa - ukusuka ^kwi-0 ukuya ^kwi-180.

4. nonconvex

iikona Non-khaxa i umlinganiselo iqondo ^malunga 181 ukuya ^malunga 359, equka.

5. Full

It is a engile ^{ngokupheleleyo} umlinganiselo degree 360.

Ezi zonke iintlobo-engile ngokobungakanani yabo. Ngoku, cinga izimvo zabo indawo-moya xa kuthelekiswa namanye.

1. olongezelelweyo

Ezi ezimbini engile etsolo, ukwenza umgca othe ngqo, oko kukuthi, sum yabo ^90.

2. eyeleleneyo

angles ezikufutshane lamiswa xa ngokusebenzisa ezicacileyo, ngakumbi ngqo, ngenxa enekona layo, ubambe umqadi kulo naliphi icala. sum yabo ilingana ^180.

3. nkqo

Iikona nkqo akhiwa kuhlangana imigca emibini. amanyathelo zabo zezidanga ngokulinganayo.

Ngoku kuziguqulela iintlobo engile ilahlwe kuthelekiswa kwisangqa. Kukho iindidi ezimbini kuphela: i oluyintloko sibhalwe.

1. Central

Yeyona iengile engundoqo kunye enekona kwi embindini wesangqa. degree yakhe umlinganiselo isidanga ubuncinane i arc, amaqela oneengxaki.

2. obhalwe

Wabhala i ikona ogama enekona amanga isangqa, amacala ngawo bawela. Lo mlinganiselo degree uyalingana isiqingatha arc apho ithembele.

Kuyinto yonke into yokwenza engile. Ngoku uyazi ukuba ukongeza edumileyo - ebukhali, yaba buthuntu, ngqo kwaye zisasazwa - geometry, kukho abanye abaninzi kweentlobo zabo.
