Pehea e huli i ka wahi o ka huinahalike ma konaʻaoʻao a me kona diagonals?

I kēia lā, kakaikahi ka poe i ike pehea e huli i ka wahi o ka huinahalike. Oiai malaila, ka mea, ua mua i loko o ka mamao i nehinei ...ʻo ia hoʻi, i kekahi manawa, i ka wa laila ua maopopo pehea e hoʻomaulia i ka wahi o ka huinahalike, no ka mea, i keia la, me he mea la ka mea e kani absurd, na nīnūnē i mau hōʻike 'ana ma o ka Internet. He mea kupanaha, e olelo aku i ka mea uuku - ia mea weliweli.

ʻO ma ke kula haʻahaʻa e ao mai ana i ka huli i ka huinahalike wahi. Akā, e pono mua aʻo, e kuhikuhi i ka wahi o ka rectangle (he ahalike - a pau ka ia rectangle, akā, me ka likeʻaoʻao).

Ua hoi i manaoia ai e kūkulu ma luna o kekahi o kekahi huinahalike ana o ka wahi o ka ana - huinahalike kenimika a me huinahalike mika. Kēia ana kahi mea heʻahā like me ka aoao like i 'ole kekahi kenimika a me hoʻokahi mika. Ke kaumaha ma muli o ka nui o ka wahi e e ana, ka mea hiki ia i ke aa, ec eioi (ʻahā like kilomika o), a Ara (he huinahalike me ka aoao o ka 100 mika, i loko o nā hua'ōlelo - "hili"). Mau mika pāhoʻonui lua, a kau hāmau i ka i ana ai i rectangle.

No ka hoʻokolohua, e lawe i ka uuku rectangle me ka aoao o ka, no kekahi laʻana, e like me 3 a me 5 mau kenimika. No ka mōakaaka pokii nā haumāna e lawelawe 'ana e kikoo aku i ke aka ma luna o ka pepa i loko o ka hīnaʻi manu, laila māheleʻana i ka rectangle laua laina ma ka lōʻihi a me ka laula, e hoonoho ana ia lakou ma ka aina o mau keena. Presumably, ke mau keena ma ka maʻamau kula puke noke hoʻopili like i kekahi kenimika. Penei, eia kahi mea akaka i ka rectangle ua maheleia iʻahā like kenimika, i ua waiho i loko o ka meaʻahā like kenimika - i ka wahi o ke ana ana.

I kekahi anu u mea e helu i nā kihikihiʻo pū i loko o ka rectangle me kaʻaoʻao o kekahi kenimika. Oe e hiki ke helu ia mua i loko o ka mau alanui, e kuhikuhi ana i kēlā me kēia lāʻau. A laila, eʻoiaʻiʻo, e hoʻohana i ka naaupo, multiplicationʻaina: loaa he elima kolamu, kela mea keia mea me ekolu mika pāhoʻonui lua. Hoonui loa ana ia lakou, ua hoopuni kiʻi 15 kapuaʻi kuea kenimika. Ma na mea hua'ōlelo, i ka wahi o kēlā me kēia rectangle mea ma ka hoonui kona lōʻihi a me ka laula.

Waiho hou i ka helu 5 ma ka "i", a me ka helu 3 ma ka «b.», Keiki loaʻa oluolu e ho oholo i ka rectangle āpana haʻilula. No laila, e huli mai ia Aloha = koi b. Akā, ia mea - he haʻilula no ka rectangle. E hoi Pono e lawe mai i ka rula, wehewehe ana, e huli i ka wahi o ka huinahalike!

It O loa na mea! ʻaoʻao o ka huinahalike e like, ka mea, 'o ia hoʻi ia oe ke puku i kaʻaoʻao "e" i loko o ka haʻilula i loko o ka "he". A laila, e nānā i ka 'aoʻao o kēia: S = koi pono. Multiplication o ka helu ana iho loaʻa i ke kahua o ka helu a me ka helu o ka lua o ka degere.

Eia naʻe, loaʻa nō nā aoao e huli i ka wahi o ka huinahalike. Keia, o ka papa, i nui makemakika pilikia. Akā, i ko lakou olelo hooholo, e hōʻike i kekahi mau haʻilula. No ka laʻana, kau e loaʻa mai pehea huli i ka wahi o ka huinahalike ole ma kaʻaoʻao, a ma ka diagonal.

E hoʻoponopono i kēia pilikia, he mea uuku ike o iniiaiie kula. Mākou, e pono i ka Pythagorean theorem. Mua, ua kükulu i ka huinahalike, e laʻa me, NMOP diagonal NO = m. E loaa mau like isosceles huinahń triangle me ka waihona ipu m.

Ana i ka luna i oleloia theorem, ua loaʻa i kaʻaoʻao o ke triangle akau. HI hana huinahā + MO = NO i loko o ka hale i loko o ka hale ma. Akā, me HI = MO, ua loaa ka hana huinahā + HI HI = NO i loko o ka hale i loko o ka hale ma. Nolaila HI 2 hana huinahā = NO ma ka huinahalike. HI E huli i ka huinahalike hiki ke NO māheleʻana i ka hale ma loko o elua.

Akā, HI ma ka huinahalike - keia mea pono i ka pane ana i ka ninau ana, e huli i ka wahi o ka huinahalike! A NO - o ka diagonal o ka huinahalike. No laila, ua hiki ke lawe mai i kekahi hou haʻilula i mai nei i ka wahi o ka hale, ua like ia me ka hapalua o kona diagonals, kūkulu i loko o ka lua o ka degere.

He hiki ke loaa i ka haʻilula loaa ia ma ka ke kahahńnai o ka kaiapili kākauʻia ma loko o laila paha circumscribed puni ia i ka huinahalike wahi. Akā,ʻaʻohe mea i pilikia iʻaʻole mākou i wehe pilikiaʻana, i ka hookumu ana, e mau loa aliʻi i ke aʻo i loko o ke kula haʻahaʻa - e hoonui aoao elua o ka rectangle, hiki e loaʻa kona wahi.
