Circle - denderedzwa ... - geometrical mufananidzo

Kuumba denderedzwa Zvinofadza kubva nemaonero kwounyanzvi, mashiripiti uye yekare rinoreva basa nayo nevanhu. kumativi ose isu duku zvinoriumba - maatomu uye mamorekuru - vari dzeraundi mu chimiro. Zuva rakatenderera, rakatenderera mwedzi, redu chakanyanya denderedzwa. The mamorekuru mvura - hwaro hwose - vanewo tenderera chimiro. Kunyange chisikigo kunoita upenyu munharaunda. Somuenzaniso, unogona kuyeuka pamusoro dendere reshiri wacho - shiri kuruka payo fomu ichi.

Izvi ndeuke pfungwa tsika yekare

Circle - chiratidzo kubatana. Hazvina aripo akasiyana siyana akawanda duku mashoko. Hatidi kunyange vachikoshesa zvikuru kukosha kuti chimiro ichi sezvo madzibaba edu akaita.

It vagara denderedzwa - chiratidzo ane mutsetse kusingaperi rinomirira nguva uye nekusingaperi. Mugore chiKristu yakanga hwekare zuva vhiri chiratidzo. Zvose pfungwa dziri nhamba iyi nerechiHebheru denderedzwa mutsetse haana mavambo uye hapana mugumo.

A nechepakati denderedzwa kwaibva zvisingaperi majana nzvimbo uye nguva yokuti navavaki. Circle - kuguma vose zvidimbu, ndicho chikonzero chaiva chakavanzika okusika nhema, maererano navavaki. Form Wachi raundi vane mufananidzo rinorevawo munhu sine wave kudzoka kusvikira mavambo.

mufananidzo uyu ane rakadzika mashiripiti uye usingaonekwi marongerwo rakapiwa kwariri vakawanda Zvizvarwa vanhu vanobva mutsika dzakasiyana. Asi chii denderedzwa sezvo munhu ari geometry?

Chii sekamufarenzi

Kazhinji pfungwa denderedzwa kuvhiringidzwa pfungwa mudenderedzwa. Hazvishamisi, sezvo vari kune mumwe akatibvunzisisa zvakabatana. Kunyange mazita avo akafanana, izvo chinoita yakawanda vavhiringidzika mupfungwa saibva vadzidzi. Kuti uzive "ndiani uyo", funga nezvemibvunzo iyi zvizere.

By tsanangudzo, denderedzwa iri munyonga riri rakavharwa, uye chimwe nechimwe pfungwa iri equidistant kubva pfungwa rinonzi pakati denderedzwa.

Zvaunofanira kuziva uye sei kuti kukwanisa kushandisa kuti tiswedere denderedzwa

Kuti uswedere denderedzwa, sarudza munhu zvemasanga ndezvokuti zvakakwana, iyo inogona kurondedzerwa se O (kuti vakawanda zvinyorwa kunotaurwa nechepakati denderedzwa, isu hatingazvirumbidzi tsaukai zvetsika notation). Chinotevera ndechokuti kushandisa nekambasi - maturusi kuti kudhirowa, chine zvikamu zviviri wakaiswa kuti mumwe nomumwe wavo kana tsono kana chinyoreso.

zvikamu zviviri izvi zviri interconnected kunoitwa hinji kuti ambotirega Pakusarudza zvemasanga siyana mukati zvimwe chokuita ne pakureba dzakawanda zvikamu izvi. Kushandisa mudziyo uyu zvemasanga pfungwa O wakaiswa vatungamirire compasses uye penzura kare circumscribed munyonga izvo pave ane denderedzwa.

Ndezvipi dzinoratidzwa denderedzwa

Kana iwe batanidza uchishandisa mutongi pakati denderedzwa uye chero zvemasanga pfungwa pamusoro munyonga apiwa somugumisiro kambasi patinonyatsonzwisisa nharaunda yacho denderedzwa. zvikamu zvose zvakadaro, akadana radii vakaenzana. Kana isu anobatana rubatsiro achirurama mutsetse mutsetse mbiri dzinokosha pamusoro denderedzwa uye pakati, tinowana dhayamita kwayo.

Nokuti kukarukureta of denderedzwa ndiyewo runozivisa kureba kwayo. Kuti tiwane zvakakodzera pakuziva dhayamita kana nharaunda yacho denderedzwa uye kushandisa nzira pasi apa.

In yemaitiro ichi, C - sekamufarenzi, R - the nharaunda yacho denderedzwa, D - dhayamita uye nhamba Pi - kugara aine kukosha 3.14.

Sezvineiwo, anoramba Pi akanga dzaona sezvo nguva kubva sekamufarenzi.

Zvakazozivikanwa kuti pasinei denderedzwa dhayamita ndiko, nhamba circumferential urefu uye zvakafanana dhayamita, akaenzana anenge 3.14.

Chii musiyano mukuru kubva sekamufarenzi ane denderedzwa

Kutaura zvazviri, denderedzwa - tambo. Hakusi mufananidzo, ndiko namahwindo munyonga mutsetse asina chinhu magumo kana kutanga. Uye nzvimbo kuti riri mukati maro - ndiko maturo. Nyore Muenzaniso circumferentially makabuda hoop kana zvakasiyana, mumwe hula-hoop, izvo vana kushandisa kurovedza muviri kana vakuru, kuti pave tetepa chiuno chomusikana.

Zvino tinosvika vanzwisise kuti denderedzwa. Izvi kuchikonzerwa mufananidzo uri mumwe akagadzirwa pfungwa, shoma mutsetse. Panyaya iyi denderedzwa sekamufarenzi mutsetse nemabasa inokurukurwa pamusoro. Zvakaratidza kuti denderedzwa - denderedzwa, pakati dzisina chinhu, uye yakatarwa muzano muchadenga. Kana iwe kudhonza pamusoro hula-hoop chinokosha, ipapo tinogona kuvazve kurimonyanisa kwaiitwa, nekuti harichazombokuberekeri denderedzwa - maturo racho akazova jira chimedu nzvimbo.

Mberi zvakananga pfungwa mudenderedzwa

Circle - geometrical mufananidzo, inova chikamu ndege kunorondedzerwa denderedzwa. Nokuti iniwo dzinoratidzwa akadai sezvo nharaunda uye dhayamita, kunokurukurwa pamusoro mune tsanangudzo denderedzwa. Uye vari dzaona saizvozvo. The nharaunda yacho denderedzwa uye nharaunda yacho denderedzwa vari akafanana pakukura. Saka, kureba dhayamita harwuna zvakafanana pose.

Sezvo denderedzwa ndiyo chikamu ndege, dzinoratidzwa munharaunda naye. Change rinogona kuzodzosera kushandisa imwe nharaunda uye nhamba Pi. The yemaitiro ndeiyi (ona. Figure pazasi).

In yemaitiro ichi, S - nharaunda, R - nharaunda yacho denderedzwa. Pi - zvakare chete chenguva akaenzana 3.14.

The yokuita denderedzwa, nokuti icho kukarukureta ndechokuti zvinogona kushandisa dhayamita shanduko uye anotora chimiro inoratidzwa zvinotevera nhamba.

Mumwe muzvina kunobva pakuti nharaunda - zviri 1/2 yacho dhayamita. Kana nharaunda akaenzana, zvinoitika kuti nhamba iri vova kutaipa:

R * R = 1/2 * D * 1/2 * D;

R * R = 1/4 * c * d.

Circle - nemifananidzo umo munhu zvikamu, kwemauto kwakadaro vangazivikanwa. Zvinoita sokuti chikamu denderedzwa, riri rakatenderedzwa ari riemukaari chidimbu yaro miviri radii nokubuda kubva pakati.

The yemaitiro runovabvumira kuverenga nzvimbo nemauto unoratidzwa zvinotevera nhamba.

Uchishandisa mukufambisira zvinetso polygons

Uyewo, denderedzwa - a geometric chimiro, izvo kazhinji rinoshandiswa nevamwe nenhamba. Somuenzaniso, akadai netriangle, mumwe trapezoid, mumwe sikweya kana rhombus. Kazhinji pane mabasa apo unofanira kuwana nzvimbo yacho yakanyorwa denderedzwa, kana, nekusiyana, anorondedzerwa dzakapoteredza imwe nhamba.

Rakanyorwa denderedzwa zvokuti kuonana kumativi ose polygon. On nerimwe divi polygon chero circumferential nguva kunyorerana inofanira kuva.

Nokuti mumwe mhando tsananguro polygon yakanyorwa denderedzwa nharaunda rinowanikwa nokushandisa mitemo yakasiyana, iyo rondedzero zvinotsanangurwa mukufamba geometry.

Mumwe anogona kumbotipa muenzaniso vashomanana vavo. The yemaitiro of denderedzwa akanyorwa polygon inogona dzaona sezvinotevera (yaifananidzira pazasi inoratidza mienzaniso).

A mienzaniso nyore zvishomanana upenyu, kuitira kusimbisa kunzwisisa kusiyana denderedzwa uye denderedzwa

Pamberi pedu ndiye munhu manhole. Kana zviri yakazaruka, ndarira pomukombero of tsotsonya - denderedzwa. Kana kuvharwa, kavha anoita somunhu denderedzwa.

Circle kunogona kunzi chero mhete - goridhe, sirivha kana zvishongo. Ring, riri wakabata boka kiyi - zvakafanana denderedzwa.

Asi kumativi magineti pamusoro firiji, dhishi kana Pancakes, akabika mbuya, ane denderedzwa.

Mutsipa Bhodhoro kana magaba mune hurongwa - ndiwo denderedzwa, asi pechifukidziro rinogumisa pamutsipa, panguva kufanana pamusoro ari denderedzwa.

Mienzaniso yakadaro izhinji, uye nokuda kuitwa kwemashoko zvavanoda kutungamirira vana nani ukabatwa kubatana dzidziso uye tsika.
