Ndeipi nechepakati symmetry?

Pfungwa yokuti "nechepakati symmetry" mufananidzo anotora kuvapo imwe nguva - pakati symmetry. On kana rutivi rwacho dziri pfungwa kunofanira mufananidzo uyu. Mumwe nomumwe wavo ane zvakafanana, ichibata parizvino.

Zvinofanira akati kuti pfungwa pakati husiri Euclidean geometry. Mugore regumi bhuku matatu namasere vaitaura ndiyo tsanangudzo spatial symmetry akabatana. Nhongonya pfungwa yokutanga akazviratidza muzana remakore rechi16.

The nechepakati symmetry aripo akadaro aizivikanwa Figures zvose, akafanana denderedzwa uye parallelogram. Uye wokutanga pakati wechipiri nhamba imwe. Nhongonya symmetry pamusoro parallelogram anoiswa panguva mharadzano pakati pemitsara zvichiitika kubva akatarisana pfungwa; mudenderedzwa - ndiwo musimboti kwake. Kutungamirira kunoratidzwa isingaperi nhamba dzakadaro. Mumwe Pfungwa angava muzinda symmetry. Mubhokisi pane rakananga mapfumbamwe ndege. Vose zvakafanana, ichibata ndege matatu perpendicular kusvikira kumucheto. Vamwe nhanhatu Pfuurai diagonal kumicheto. Zvisinei, pane mufananidzo kuti haana imwe. It chinhu zvemasanga Triangle.

Mune mamwe mashoko okuti "nechepakati symmetry" rinorondedzerwa sezvinotevera: kuva muviri geometric (Nhamba) anonzi kuti zvakafanana, ichibata noruremekedzo kuti centre C, kana mumwe pfungwa A muviri une pfungwa E akarara mukati iyoyo nhamba zvokuti kwavatumwa chidimbu achipfuura With pakati, kuti vaiguranye hafu. pane vakaenzana urefu kuti nhengo yegwara pfungwa.

Nhengo pamakona ose sezvikamu maviri nechipi, iyo pane musimboti symmetry zvakare vakaenzana. Nhamba mbiri avete mativi ose nepakati pfungwa, muchiitiko ichi, inogona seari pane mumwe. Zvisinei, zvinofanira kutaurwa kuti chikumbiro rinoitwa munzira chaiyo. Kusiyana mugirazi, ine symmetry anotora majana nomutezo mumwe mufananidzo zana namakumi masere madhigirii akapoteredza pakati. Saka, chikamu chimwe vanoridza kupinda nzvimbo hama rechipiri girazi. Maviri nechipi vanogona kunzi musi mumwe, outputting kubva vanhuwo ndege.

In nemasvomhu izuchenin shamisa uye kunyange mabasa kunze uchishandisa calculators. Nokuti chinhu kunyange basa girafu inovakwa symmetrically panyaya rinoronga namasanhu. For Zvinoshamisa - toreva zvokusvika mavambo, kuti ndiye O. Saka, nokuti vasinganzwisisike basa tinoberekwa nechepakati symmetry, uye nokuda kunyange - akabatana.

The huru symmetry chinoreva kuti ndege nhamba akabatana kuti symmetry kurongeka maviri. Panyaya iyi, akabatana ucharara perpendicular kuti ndege.

Zvakajairika mazuva chakagadzirwa symmetry zvakasikwa. inogona kuwanika zvezvisarudzo wakakwana mienzaniso zvakasiyana-siyana zvakawanda. mapatani izvi, ziso-kuona marudzi akasiyana zvinomera, mollusks, tumbuyu, uye mhuka dzakawanda. Murume kufarira runako munhu maruva, petals, Zvinoshamisa wakakwana igadzire muzinga urongwa pamusoro chivharo sunflower mbeu, mashizha pamusoro chirimwa hunde ose. The nechepakati symmetry muupenyu ubiquitous.
