Yintoni le bhokisi? iimeko ethile yoqala

Geography, ibhayoloji, imichiza, algebra, geometry ... Abafundi kufuneka banyamezele ulwazi oluninzi evela ezahlukeneyo zenzululwazi. Nakuba kunjalo, kukho iindawo lolwazi, nto leyo ilula ngokwaneleyo ukuze baqonde, aqhelekileyo kunye nemithetho zabo ezisisiseko. Ezi ziquka wew geometry. Ukuze ukwazi zonke iinkcukacha zale inzululwazi, kuyimfuneko ukuba simazi zalo ezisisiseko, elikuwo na. Ngapha koko, ngaphandle iziseko geometry ndawo.

definition yoxande

Uxande - a imilo zejometri kunye engile ezine ekunene. Ingcaciso ilula, kodwa musa ukucinga ukuba abafundi abanalo iingxaki ukufunda izihloko ezinjalo, ngokuba kukho iqela lemisebenzi esemqoka. Imilinganiselo uxande zixhomekeke ubude macala omabini, ezo amaninzi luchazwa ngegama Latin kunye kunye b.

iipropati uxande

• icala ilele phezu komnye ngokulinganayo parallel;
• amanani oxwesileyo bayalingana;
• kwinqanaba ekudibaneni kwe-idayagonali kubachithachitha kwisiqingatha;
• uxande lungahlulwa-hlulwa zibe ezimbini ngokulinganayo oonxantathu tye.

iimpawu ze unxantathu

Kukho osemqoka ezintathu kuphela ophethwe uxande. Nazi ke:

• parallelogram kunye idayagonali alinganayo - yoxande;
• parallelogram nge angle omnye ngasekunene - yinto uxande;
• quadrangle kunye engile ezintathu ekunene - yoxande.

A kancinane ezinomdla kakhulu

Ngoko ke, yintoni na uxande, ke ngoku icace, kodwa yintoni indima anazo iingxaki zejometri enikuqwalaseleyo practice ekusafuneka ukuqonda. Ngoko ke, okokuqala zonke ndimele ndithi ukuba lo ngoyena lula zejiyometri, ngazo walhule le ndawo ibe ngamacandelo kwaye kwiindawo ezivulekileyo, yaye ngaphakathi. Yintoni le bhokisi? Njengoko usazi, yena a quadrangle. Kukho iintlobo ezininzi yokugqibela, phakathi kuzo neemvumi (emacaleni kuphela ezimbini Ndikulinganise), i parallelogram (ngapha nangapha parallel), isikwere (zonke iikona kwaye amacala efanayo), idayimani (parallelogram enamacala alinganayo), kunye nabanye. Ityala ekhethekileyo uxande na isikwere, apho zonke engile ezi engile, namacala bayalingana.

Asikwazi ukuba le uxande, singasathethi indlela ukufumanisa ubukhulu bayo. Ummandla lo mzobo zejometri kucingwa ukuba imveliso ububanzi bayo ubude kunye kujikelezo iyafana naleyo nokuba yiyiphi, lingana umdibaniso ubude macala onke. Kulo mzekelo, oku kwakhona ulingana kabini inani ubude nobubanzi, ngokuba kumacala ephikisanayo uxande iyalingana. Ngoku uyazi ukuba yintoni uxande kwaye ukwenza ngayo, zokusombulula iingxaki nokufunda iimfihlelo kwale nzululwazi twi yaye kungakholeleki, njengoko geometry.
