Kev txiav txim 2

Tib neeg kuj nug, qhov kev txiav txim ntawm kev sib hloov symmetry rau daim duab yog dab tsi?

Cov kev txiav txim ntawm rotational symmetry ntawm ib tug geometric daim duab yog tus naj npawb ntawm lub sij hawm koj tuaj yeem tig lub geometric daim duab kom nws zoo nkaus li zoo ib yam li tus thawj daim duab . Koj tsuas tuaj yeem tig lub daim duab mus txog 360 degrees. Cia peb pib nrog ib tug zoo uas muaj ib tug kev txiav txim ntawm rotational symmetry ntawm 1.

Qhov thib ob, qhov kev txiav txim ntawm kev sib hloov symmetry ntawm trapezium yog dab tsi? A trapezium muaj ib tug khub ntawm parallel sab. Qee cov trapeziums muaj ib kab ntawm symmetry . Lawv hu ua isosceles trapeziums vim lawv muaj ob sab sib npaug zoo li isosceles daim duab peb sab. A trapezium muaj kev sib hloov symmetry ntawm xaj ib.

Kuj nug, qhov kev txiav txim ntawm kev sib hloov symmetry ntawm daim duab peb sab isosceles yog dab tsi?

Order 1

Dab tsi yog qhov kev txiav txim ntawm rotational symmetry ntawm oval?

Raws li tau piav nyob rau hauv lub ntsiab txhais, peb yuav tsum tau xyuas, pes tsawg zaus ib ellipse fits rau nws tus kheej thaum lub sij hawm tag nrho kev sib hloov ntawm 360 degrees. Thaum peb saib cov duab saum toj no ntawm ellipse , nws haum rau nws tus kheej 2 lub sij hawm thaum lub sij hawm tag nrho kev sib hloov ntawm 360 degrees. Li no, ib ellipse muaj kev sib hloov symmetry ntawm xaj 2.
