Pehea e huli i ka mamao ma ka i kahi kūlike o pelane

Ma makemakika, ka hōʻailona helu a me ka anahonua hoʻonoho hana o loaa i ka mamao i ka wahi a me ka laina pololei mai ka hoakaka mea. He loa keʻano o ka aoao, ka mea i waeʻia o ka i hilinaʻi nui ma luna o ka hoʻokomo oʻikepili. E hoomanao i ke ano, e huli i ka mamao ma waena o hoʻoholo ma mua o nä mea i loko o kekahi ana.

Ke hoʻohana no ana mea

Ma ka loiloi mua kahua o ka? Acaeoey o makemakika i ao mai pehea e hoʻohana walaʻauʻana hana (e like me ke aliʻi, protractor, panana, triangle, etc.). E huli i ka mamao ma waena o nui a me ka pololei a me kā lākou kōkua, he mama. Lawa ia e ka pālākiō o ka papa, a kākau i ka pane. Hoʻokahi wale nō i ka ike i ka mamao mea like me ka lōʻihi o ka pololei o ka laina hiki e holo ana ma waena o nā kumu, a me ka hihia o laua laina - ÷ haku ma waena o lākou.

E ho ohana i anahonua theorems a me axioms

Ma ke kula kiʻekiʻe, aʻo e ana i ka mamao o me ka hoʻohana kūikawā hana a kaiapili pepa. Kēia pono lehulehu theorems, axioms a me ka hoike. Pinepine, i ka pilikia o ana, e huli i ka mamao, emi ke kahua o ka triangle akau , a me ka huli ana i kona aoao. E hoʻoponopono i kēia mau pilikia i ka Pythagorean theorem lawa waiwai o triangle mauna a me kāu kiʻina hana o ka huli ana.

Nā kumu ma ka i kahi kūlike o pelane

Inā loaʻa nō nā heluʻai, a hāʻawi lākou hoʻomoana ma ka i kahi kūlike o lipi, laila, pehea e huli i ka mamao mai kekahi i ka mea'ē aʻe? Ka pāʻoihana e komo i loko o kekahi mau kahua o ka hoʻonaʻauao.

1. Laina e na kumu, a me ka lōʻihi o ka a, e ia i ka mamao ma waena o lākou.
2. E huli i ke koena unuhi o kahi kūlike o aiee o nā kumu (k, P) o kēlā me kēia (axis). | He ₁ - he ₂ | = D ₁ a | R ₁ - R ₂ | = D ₂ (modulo cia lawe, mai ka mamao hiki ole e io) .
3. Mahope, i ka kūpono loa i ka kukulu ana, a loaʻa lākou huinahalike huina: _D1 ² + b _{² February}
4. Ka hope loa anu u, e ia e extract i ka huinahalike kumu o ka kūpono helu. Kēia e ia i ka mamao ma waena o kumu: D = V _{(D1 D2} ² + ^2).

E like me ka hopena, i ka pāʻoihana holoʻokoʻa ua lawe mai ma ka hookahi haʻilula, kahi o ka mamao mea like i ka huinahalike kumu o ka huina o ka hana huinahā oko o nā wahi:

b = V (| he ₁ - he ₂ | ² + | k ₁ - P ₂ | ²⁾

Inā 'oe i kekahi mea e pili ana pehea e huli i ka mamao mai kekahi wahi a hiki i kekahi i loko o ekolu-dimensional wa, i ka huli' ana no ka pane no ka mea, mea,ʻaʻole loa okoa mai ka luna. Ka olelo hooholo e e ma muli o ka mea kēia haʻilula:

b = V (| he ₁ - he ₂ | ² + | k ₁ - P ₂ | ² + | [illegible] ₁ - [illegible] ₂ | ²⁾

laua laina

A p ÷ haku e holo ana mai kekahi wahi e moe ana ma ka pololei o ka laina, ia laua i, a me ia e ia i ka mamao. I ka hoʻoponopono pilikia i loko o ka pelane oe pono e huli i nā wahi o kekahi wahi o kekahi o na laina. A laila e huli i ka mamao mai ka mea, a hiki i ka lua o ka laina. E hana i kēia, ke hāʻawi aku iā lākou pololei a hiki i ka nui helu kaulike o ka palapala koi + By + C = 0. Mai na waiwai o laua laina ike e i coefficients A a me B i like. Ma keia hihia, huli i ka mamao ma waena o ka laua laina hiki e ana o ka haʻilula:

b = | C ₁ - C ₂ | / V (A ² + B ²⁾

Pela, i mai la i ka ninau o ke ana, e huli i ka mamao mai ka pale e hoopii mai ai, e pono e alakaʻiʻia e nā kūlana o ka pilikia a me ka hoʻolako i ka hana e hoʻoponopono i ia. Mea hiki e like ana i na mea maalea, a me ka theorems a me nā papakuhikuhi.
