Pehea e loaʻa i ka geometric huinahalike kinona

Aia i ka mana loa o ka helu pelane na kii o kekahi mau kinona like pono a me ka hewa. Ka e like me ka waiwai o nā mea a pau i nā'āpana - kela mea keia mea o lakou mai ka wahi. Square ano - o ka nui o ka pelane noho ma kēia mau kii, i hoike ia ma kekahi mau huahelu. Keia waiwai ua mau olelo ma ka maikaʻi helu. Ke pa alima o ka ana o ka wahi o ka huinahalike, nona kaʻaoʻao lōʻihi mea like i kekahi (e laʻa me, hoʻokahi mika a me kekahi kenimika). He kokekau wale 'āpana o kekahi shape hiki ke ho omaulia ma ka hoonui i ka helu o ka pa alima kihikihiʻo loko i ka mea, ua maheleia ma luna o ka wahi o kekahi huinahalike.

Other wehewehe o ka manaʻo like penei:

1. Square ano kinona - scalar maikaʻi Hawaiʻi satisfying ana:

- i like na apana - like me ka nui o ka wahi;

- ina ka huahelu ua maheleia i māhele (na mea kii), kona wahi - i ka huina o mika pāhoʻonui lua o kaʻikepili mau'āpana;

- heʻahā like me kaʻaoʻao o ka mokuna, o ka pa alima wahi.

2. Square eiiieaena shape kinona (polygons) - maikaʻi cia me ka waiwai:

- i like polygons - ka ia aiee o ka wahi;

- ina ka iieeaii i kekahi mau 'ē polygons me ka wahi like me ka huina o ka hope a puni. Keia rula i hoʻopaʻa oiaio no ole-overlapping polygons.

E like me ka maliuia axiom māmala'ōlelo no i ke ano o ka wahi (polygons) - maikaʻi nā loina.

Hoomaopopo ana i ka wahi o ka p ÷ ai ua haawiia kaawale ka mea, imi ae la ia e ka wahi o ka papa iieeaii kākauʻia i loko o ka kaiapili o koʻikoʻi a hanohano - hoʻowahāwahā i ka mea i ka helu o kona aoao mālama i ka infinity.

Square na apana o ole shape (ākeʻakeʻa kumu kinona) i ole ho'ākāka 'ana wale ka manao ana o ko lakou mau ki ina hana like o ka ho omaulia.

I ka ho omaulia ana o ka wahi i loko o ka wā kahiko ua he nui mea hiki pilikia i ka hoomaopopo ana i ka nui o ka aina. Na rula no ka helu ana i ka wahi o kekahi mau haneri makahiki BC, ua ua ua kālaiʻia e ka Greekʻepekema, a i ho'ākāka 'ia i loko o ka "hehee wale" o Euclid like theorems. Interestingly, na rula no ka hoomaopopo ana i ka mau o ka poe noonoo ole kinona i loko o ia mau mea - o ka ia me i keia manawa. Mika pāhoʻonui lua geometric kinona me he uma contour, mau hōʻailona i hoʻohana 'kali.

Ka i ka ho omaulia ana o na mau mea o ka poe noonoo ole kinona (triangle, rectangle, heʻahā like), maʻa i nā mea a pau, mai ke kula, e lawa. Kohoʻia i loaʻa i hoʻopaʻanaʻau palapala designations haʻilula huahelu mau mea. Nui ka mea, e hoomanao i kekahi mau mea rula:

1. No ka ho omaulia i ka wahi o ka huinahalike, he mea pono e hoonui i kaʻaoʻao lōʻihi ma luna iho ( 'ole e kūkulu i loko o ka lua o ka degere).

2. O ka wahi o ka rectangle he pōpilikia ma ka hoonui i ka loa ma ka laula. He mea pono i ka lōʻihi, a me ka laula i hoikeia ma ka ia naehana.

3. ka wahi o ka luna 'huahelu he pōpilikia ma ka mahele ana i ka mea i loko o kekahi mau mea, a hoʻokomo i ka kūpono wahi.

4. O ka nui o ka rectangle i hookaawale ia i loko o nā triangle mauna kona mau mea i kau like, a ua like no ka hapalua o kona wahi.

5. ka wahi o ka triangle he pōpilikia me ka hapalua o ka huina hoonui o kona kiekie, a he kumu.

6. ka wahi o ka hoa kanaka, ua like no ka huina hoonui o ka hale o ke kahahńnai i nā mea a pau kekahi helu o «π».

7. e huli i ka wahi o ka parallelogram like me ka huina hoonui o ka pili aoao, a me ka sine o ka huina e moe ana ma waena o lākou.

8. Area o ka rhombus - ½ i ka hopena o ka hoonui i ka sine o na diagonals o ka maloko huina.

9. ka wahi o ka trapezoid loaʻa hoonui loa kona kiekie ma ka centerline loa i mea like me ka makemakika mawaena o na kumu. Kekahiʻano o ka ho'ākāka 'āpana o ke trapezoid - hoonui i ka'ōpū mai diagonal a me ka sinus ka makau e moe ana ma waena o lākou.

Children ma ke kula haʻahaʻa, no ka mōakaaka, ua pinepine haawiia hana: e loaʻa i ka wahi e holo ana ma luna o ka pepa kinona hoʻohana pallets paha kuina o ka aniani moakaka pepa o ka moe ma luna keena. Oia pepa ua superimposed ma ka i ana ai i ke kinona ua noʻonoʻo pono i ka helu o ka huina aeee (huahelu o ka wahi), e hoonoho ana ia i loko o ka loop, alaila o ka helu o ke kāpili, a ua maheleia ka hapalua.
