Cov kab dotted hauv nruab nrab ntawm tsab ntawv A, hauv qab no, hu ua daim iav kab , vim yog tias koj tso daim iav raws nws, qhov kev xav zoo li zoo ib yam li tus thawj. Lwm lub npe rau daim iav kab yog ib kab ntawm symmetry . Hom no symmetry kuj hu ua reflective symmetry los yog xav txog symmetry.
Ntawm no, rau daim duab twg yog kab dashed kab ntawm symmetry?
Txhua daim duab peb sab isosceles muaj kab symmetry . Cov dashed kab sawv cev kab ntawm symmetry , thiab cwb puab yog hais tias yog symmetrical txog qhov no kab . A puab tuaj yeem muaj ntau tshaj ib kab ntawm symmetry . Yog li ib daim duab plaub muaj ob kab ntawm symmetry , ib daim duab peb sab sib npaug muaj peb kab ntawm symmetry , thiab ib square muaj plaub.
Tsis tas li ntawd, kab symmetry yog dab tsi? Cov " Kab ntawm Symmetry "(pom ntawm no dawb) yog qhov kev xav kab qhov twg koj tuaj yeem quav cov duab thiab muaj ob qho tib si sib luag. Saib: Symmetry . Kev xav Symmetry.
Raws li txoj cai, kuv yuav nrhiav tau txoj kab ntawm symmetry li cas?
Rau nrhiav tus kab ntawm symmetry algebraically, koj yuav tsum txheeb xyuas yog tias tus kev sib npaug yog sau nyob rau hauv tus qauv daim ntawv los yog vertex daim ntawv. Cov qauv qauv yog y = ax^2 + bx + c, qhov twg a, b, thiab c sib npaug txhua tus lej tiag. Koj tuaj yeem siv lub qauv x = -b/2a nrhiav tus kab ntawm symmetry.
Puas yog txoj kab xiav zoo li yog kab ntawm symmetry?
Yog, vim lub kab xiav faib cov duab rau hauv 2, uas qhia tias cov duab yog symmetrical los tsis.

Puas yog tag nrho cov quadrilaterals muaj ib txoj kab ntawm symmetry?
Ib txoj kab uas qhia txog ib daim duab rau nws tus kheej yog hu ua kab ntawm symmetry. Ib daim duab uas tuaj yeem nqa mus rau nws tus kheej los ntawm kev sib hloov yog hais tias muaj kev sib hloov symmetry. Txhua plaub-sided polygon yog quadrilateral
Puas yog tsab ntawv N puas muaj ib txoj kab ntawm symmetry?
Cov tsiaj ntawv zoo li B thiab D muaj kab rov tav ntawm symmetry: lawv sab saum toj thiab hauv qab qhov sib tw. Qee cov tsiaj ntawv, piv txwv li, X, H, thiab O, muaj ob txoj kab ntsug thiab kab rov tav ntawm symmetry. Thiab qee qhov, zoo li P, R, thiab N, tsis muaj kab sib luag
Puas yog daim duab peb sab muaj ib txoj kab ntawm symmetry?
Daim duab peb sab txoj cai, yog tias nws yog isosceles txoj cai kaum sab xis ces nws yuav muaj ib kab ntawm symmetry. Yog hais tias nws yog equilateral txoj cai angled daim duab peb sab ces nws yuav muaj peb kab ntawm symmetry. Yog hais tias nws yog scalene txoj cai angled daim duab peb sab ces nws yuav tsis muaj kab ntawm symmetry
