Indlela yokufumana iimilo zejiyometri square

Kukho inani olungenasiphelo yamanani moya iimilo ezahlukeneyo njengoko okulungileyo nokubi. Ipropati efanayo zonke iinyama - ngamnye kubo ndawo. iimilo Square - ke ubungakanani moya zihlala la manani, ichazwe kumacandelo athile. Eli xabiso lusoloko kuboniswa okanye linani elidibanisayo. Iyunithi yomlinganiselo yi ariya isikwere, ubude ogama icala ilingana ukuya kwenye (umz, imitha enye okanye sentimitha enye). indawo eyiyona nayiphi imilo kungabalelwa phinda inani yeyunithi izikwere angena kuyo lohlulwe kwindawo ye-square omnye.

Ezinye iinkcazelo ingqiqo ngolu hlobo lulandelayo:

1. iimilo Square ezilula - scalar amaxabiso alungayo iimeko ezanelisayo:

- ube ngamaqhekeza alinganayo - elingana nexabiso le ndawo;

- ukuba mzobo yahlulwe (amanani ezilula), indawo yayo - udibaniso lwezikweri zonke amaqhosha data;

- ngesikwere kokuba icala yunithi, i indawo unit.

2. Square iimilo imilo esimbaxa (eneepoligoni) - amaxabiso alungayo ukuba iimpawu:

- babe yeepoligoni alinganayo - imilinganiselo efanayo kule ndawo;

- Ukuba polygon ambalwa nezinye eneepoligoni kunye kwindawo elingana sum of kwisithuba lokugqibela. Lo mthetho ibamba kuyinyaniso ukuba yeepolygons non-zidlulela.

Njengoko i ingxelo saziwe wavuma ukuba abumbe ndawo (iipolygons) - amaxabiso alungayo.

Ukumisela kummandla isangqa anikwe ngokwahlukeneyo ubuninzi wafuna yi kummandla we yipolygon abhaliwe isangqa sekile - nangona inani lamacala ayo usoloko yokungapheli.

iziqwenga Square semilo engagunyaziswanga (iimilo engenasizathu) akukho nkcazelo kumiselwa kuphela iindlela zabo yokubala.

Ukubalwa ndawo kumaxesha amandulo ingxaki ngokwenza ebalulekileyo ekumiseleni ubungakanani komhlaba. Imithetho yokubala kummandla embalwa, iminyaka emakhulu BC, ziye ziqulunqwe zizazinzulu yamaGrike kwaye ochazwe "Elements" of Euclid njengoko theorems. Okubangel 'umdla kukuba, imithetho yokuqingqa iindawo zeemilo ezilula kuzo - ngokufanayo okwangoku. Izikwere iimilo zejiyometri ukuba aya egosogoso, ibalwe kusetyenziswa umda.

Ukubalwa iindawo ezilula iimilo (unxantathu, uxande, isikwere), eziqhelekileyo kubo bonke esikolweni, nje ngokwaneleyo. Ukukhetha equlethe nokuba ngentloko ileta izihionipho ifomula amanani iindawo. Kwanele ukuba ukukhumbula imithetho embalwa elula:

1. Ukubala ndawo isikwere, kuyimfuneko zande kwicala elide phezu ngokwalo (okanye ukwakha isidanga sesibini).

2. Ummandla uxande ibalwa phinda ubude nobubanzi. Kuyimfuneko ukuba ubude kunye ububanzi zazikho iiyunithi efanayo.

3. Ummandla isafobe oluntsonkothileyo kubalwa ngokwahlula-hlula libe ezilula eziliqela uzidibanise ndawo ngenxa.

4. Ubukhulu uxande iyahlula libe oonxantathu ababini iindawo bayalingana yaye ulingana isiqingatha kwindawo yayo.

5. Ummandla unxantathu libalwa nje ngesiqingatha imveliso ye ukuphakama kwalo kunye kwisiseko.

6. Ummandla isangqa ilingana imveliso isikweri umgama ngalo lonke inani elithile «π».

7. ukubala indawo ye parallelogram njengoko imveliso kumacala ezikufuphi kwaye i sine ye-engile elele phakathi kwabo.

8. Area of a irhombus - ½ umphumo phinda i sine ye idayagonali-angle lwangaphakathi.

9. Ummandla trapezoid ukufumana phinda ukuphakama kwalo phezu ubude ekumbindi leyo ilingana imin lokubala eliguqukayo iziseko. Enye ngumfuziselo kummandla ingcaciso trapezoid - phinda isizalo oxwesileyo kunye sinus engile elele phakathi kwabo.

Abantwana kwisikolo samabanga aphantsi, ecacileyo, basoloko imisebenzi sona: ukufumana indawo ezotyiweyo iimilo zamaphepha usebenzisa pallets okanye Iphepha ngaphaya kwe erhangqwe kwiiseli. iphepha olunjalo enyanzeliswa phezu kwesimo elilinganisiweyo ithathwa inani leeseli elipheleleyo (iiyunithi of ndawo), uyibeka ngokwenzekayo, ngoko ke inani aziphelelanga, lwahlulwe kwisiqingatha.
