Kodi kupeza mtunda pa ntchito ndege

Mu masamu, ndi ajebura ndi Masamu akonzedwa ntchito chopeza mtunda mfundo kapena mzere molunjika ku chinthu mwasankha. Ndi ndithu m'njira zosiyanasiyana, kusankha potsata deta athandizira. Tikambirana momwe kupeza mtunda wa pakati zinthu anakonzeratu zinthu zosiyanasiyana.

Ntchito kuyeza zida

Pa siteji koyamba za chitukuko cha masamu amaphunzitsidwa mmene ntchito zida zikuluzikulu (monga mtsogoleri, protractor, kampasi, makona, etc.). Pezani mtunda pakati pa mfundo kapena molunjika ndi thandizo lawo n'kosavuta. Zokwanira kuti lonse zopatutsana ndi kulemba yankho. Mmodzi yekha ali kudziwa kuti patali ndi wofanana ndi kutalika kwa mzere wolunjika angaonere pakati pa mfundo ndi mu nkhani ya mizere yomweyi - perpendicular pakati pawo.

Kugwiritsa Masamu theorems ndi axioms

Mu sekondale, kuphunzira kuyeza mtunda wopanda ntchito zipangizo zapadera kapena pepala Zithunzi. Izi zimafuna theorems ambiri, axioms ndi zitsimikizo. Nthawi zambiri, vuto la momwe kupeza mtunda, kuchepetsa mapangidwe kansalu lamanja , ndi kufunafuna chipani chake. Kuti athetse mavuto amenewa kudziwa Pythagorean Lingaliro Lovomerezeka zokwanira katundu wa Triangles ndi njira za kutembenuka.

Mfundo pa ntchito ndege

Ngati pali mfundo ziwiri ndipo anapatsidwa udindo wawo pa ntchito nkhwangwa Nanga kupeza mtunda kuchokera wina ndi mzake? Yankho adzaphatikizapo magawo angapo:

1. Mzere kulumikiza mfundo, ndi utali umene adzakhala mtunda wa pakati pawo.
2. Pezani kusiyana kwa ntchito mfundo za mfundo (k, p) aliyense olamulira: | ₁ - ₂ | = D ₁ ndipo | r Mukhoza ₁ - r Mukhoza ₂ | = D ₂ (makhalidwe modulo kutenga, kuyambira patali sangakhale zoipa) .
3. Kenako, manambala chifukwa mu akuika ndi kupeza ndalama zawo lalikulu: _D1 ² + D _{² February}
4. Chinthu chomaliza adzakhala kuchotsa muzu lalikulu la nambala chifukwa. Chimenechi chidzakhala mtunda pakati pa mfundo: D = V _{(D1 D2} ² + ^2).

Chifukwa cha zimenezi, njira yonse ikuchitika mfundo imodzi, pamene mtunda ndi wofanana ndi muzu lalikulu Muwerenge kusiyana lofanana mbali zonse za ndondomeko:

D = V (| ₁ - ₂ | ² + | tsa ₁ - tsa ₂ | ²⁾

Ngati muli ndi funso za mmene kupeza mtunda mfundo wina ndi mzake mu malo atatu azithunzi omwe tikunena, kufufuza yankho si wosiyana kwambiri pamwamba. Chigamulo udzakhala wokhazikika pa chilinganizo zotsatirazi:

D = V (| ₁ - ₂ | ² + | tsa ₁ - tsa ₂ | ² + | f ₁ - F ₂ | ²⁾

mizere kufanana

A perpendicular limachokera ku Msikiti atagona pa mzere woongoka, ikufanana, ndipo adzakhala mtunda. Pamene kuthetsa mavuto ndege muyenera kupeza ndondomeko ya Msikiti mmodzi wa mizere. Ndiyeno kuwerengetsa mtunda kuchokera kwa mzere wachiwiri. Kuti tichite zimenezi, tiwapatsa kulongosola kuti anthu aone kuti pali ambiri a mtundu nkhwangwa + Mwa + C = 0. Kuchokera katundu wa mizere kufanana kudziwika kuti koefishienti A ndi B ofanana. Pankhaniyi, kupeza mtunda wa pakati pa mizere kufanana angakhale njira:

D = | C ₁ - C ₂ | / V (A ² + B ²⁾

Motero, mafunso a mmene kupeza mtunda kuchokera chandamale chinthu, muyenera kutsogoleredwa ndi zikhalidwe za vuto ndi mabuku okuthandizani kuti kulikonza ilo. Iwo akhoza kukhala zipangizo kuyeza, ndi theorems ndi kachitidwe.
