How kuwana mukomberedzo ane rectangle kumativi aro, pamusoro nzvimbo, uye rimwe divi pakona pakati ayo diagonal uye kurutivi rectangle

Kazhinji muupenyu, vanhu vanofanira kuwana mukomberedzo ane rectangle. dambudziko iri unomuka, somuenzaniso, mune zviitiko apo unofanira kuverenga urefu fenzi kana mari inodiwa pasting wallpaper mumadziro mumba. Zvisinei, mukupera zvazvingava, mukomberedzo ndiyo chete murevereri mhinduro dzinoshanda mabasa. Asi, zvakadaro, muchiitiko ichi, vanhu vanofanira kuziva sei kuwana mukomberedzo ane rectangle.

Chokutanga, ndinoda kutsanangura kuti chinonzi ari mukomberedzo. Mukomberedzo, chokwadi, muganhu imwe geometric chimiro kana Kureba pamiganhu yayo. Zvino kutsanangura zvinorehwa rectangle. Parallelogram rworudyi pamakona anofanira akataura mabhokisi. Chaizvoizvo, chikuru chikabviswa vari chaizvo ayo pamakona, izvo zvinofanira kuva geometric mufananidzo mana.

Saka, kuti kuwana zvachose pakureba kumuganhu rectangle, unofanira kuwedzera vakakwira urefu zvose nokunhivi dzayo. Sezvataona, yakafanana kumativi rectangle vakaenzana, saka kuti zviite kunzwisisa zvinofanira kunzwisiswa kunofanira, kuti mukomberedzo ane rectangle akaenzana kaviri Verengai dzayo mbiri panhivi.

Kuti zvijeke, kureva vakaenzana kumativi mubhokisi tsamba Latin arufabheti "munhu" uye "b" azvaitwa. Saka, zvinoita sokuti P (rectangular mukomberedzo) = munhu + b + mumwe + b. mukana wokuti vanhu vanga Izvi zvinogona tinoshandurirwa mutoo: P = 2 × (a + b).

Asi kazhinji muupenyu, pane nguva apo tinoziva Kureba chete rumwe, uye mimwe mitezo bhokisi, kana kunze kwayo. Chimboona mikana mishoma.

Somuenzaniso, tinofanira kufunga chii mukomberedzo ane rectangle, chero kuti pakureba rimwe divi rectangle harizivikanwi, asi inozivikanwa kuti nharaunda yayo. Zvakakodzera, achishandisa nzira kuti pakuverenga nzvimbo imwe rectangle riri akaenzana chigadzirwa kumativi acho, ngaaverenge kureba rwayo rwechipiri. zviri nyore ichi chakaitwa kupatsanura imwe nzvimbo iri imwe chinoumba. Kuziva mativi ose rectangle inogona nyore akaverenga, uye ayo mukomberedzo.

musimboti Izvi akakodzera kana pakuverenga uwandu zvinhu zvinodiwa fenzi mugove, kana nzvimbo raanotaura mapepa. Mumwe ane chete anowedzera kuyera rimwe divi mugove. Asi dzimwe nguva unofanira kuziva sei kuwana mukomberedzo ane rectangle, kana uchiziva mumwe kumativi ari rectangle wayo diagonal.

Sezvingatarisirwa, wokutanga computation danho iri kuwana urefu kurutivi rectangle wechipiri. Inogona dzaona kubudikidza Pythagorean theorem no, iyo inoti kuti hypotenuse pakati netriangle zvakarurama, yakavakwa muchivara, rinosanganisira vakaverenga dzinoungana rwemberi. Saka, tinofanira kuverenga urefu diagonal twasu uye anozivikanwa divi yakareba sikweya, ipapo kuwana musiyano pakati pavo, uye kubva musiyano uyu anofanira kuva kutora mativi mudzi.

The zvichiguma mativi midzi uye achava vasingazivikanwi divi kureba. Uye sei kuwana mukomberedzo ane rectangle inogona akapeta kuzivikanwa divi urefu uye doubling navo, vose vaigona nyore kukurira izvi.

Masvomhu kirasi ari kufunga sei kuwana mukomberedzo munhu rectangle pamusoro chidzitiro diagonal uye mumwe rikwanise angled inoumbwa diagonal uye rimwe divi rectangle. Pano tine chaiwo muenzaniso wokushandiswa dzemaitirwe of Sine. Kubva kuchikoro tose tinoziva kuti Sine pakati rekona ane netriangle rworudyi vakaenzana nhamba yacho pedyo gumbo uye hypotenuse. Nokudaro fomura: chivi X = cathetus: hypotenuse (diagonals yacho rectangle).

Sinus nyore kucherechedzwa kubudikidza Bradis tafura, nzira yemaitiro anozivikanwa ukoshi akaiswa Tsanga yacho yaichekwa - hypotenuse, uye zviri nyore computed, mumwe kumativi rectangle. Zvino danho iri uchiwana kurutivi rectangle wechipiri. Pane inures musimboti uchishandisa Pifogora theorem no inokurukurwa pamusoro. Squaring kuzivikanwa diagonal uye bvisa kubva akagamuchira mativi ose vakawana divi. Kubva kwaiita mativi mudzi. By ikozvino kuzivikanwa mativi anogona ngaaverenge mukomberedzo, akapeta kureba dzavo uye doubling.

Sezvingatarisirwa, izvi hazvisi dzoga shanduro mienzaniso Chokwadi, pane zvakawanda, asi rakajairika zvinorondedzerwa pamusoro.

Saka, zvinogona vakagumisa kuti pasina nokuziva urefu mbiri dzakafanana mativi rectangle kuti rinotsanangura mukomberedzo kwakaoma zvisingaiti. Zvisinei, kushandisa zvombo kuti geometrical theorems uye axioms, zvinokwanisika nguva kuverenga mukomberedzo ane rectangle, akapeta nenhumbi dzayo kumativi.
