Ob kab ntawm Symmetry : Qee daim duab tuaj yeem muab faib ua ob sib npaug qhov chaw nrog ob kab . Cov duab no tau hais tias muaj Ob kab ntawm Symmetry . Cov duab plaub yog ib qho piv txwv ntawm Ob Kab ntawm Symmetry . Lub Rectangle tuaj yeem muab faib ua vertically, kab rov tav lossis diagonally kom tau txais ob symmetrical ntu.
Raws li, cov duab twg muaj 2 kab ntawm symmetry?
Daim duab plaub
Tsis tas li ntawd, dab tsi quadrilateral muaj 2 kab ntawm symmetry? Rhombus. Ib lub rhombus muaj ob kab ntawm symmetry.
Raws li, 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.
Yuav ua li cas koj nrhiav tau txoj kab ntawm symmetry?
Yuav nrhiav tau kab ntawm symmetry algebraically, koj yuav tsum txheeb xyuas seb qhov sib npaug yog sau rau hauv daim ntawv qauv lossis daim ntawv vertex. 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 tus qauv x = -b / 2a los nrhiav cov kab ntawm symmetry.

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
Dab tsi yog qhov txawv ntawm tus kab mob los ntawm tus kab mob?
Qhov sib txawv tseem ceeb ntawm tus kab mob thiab tus kab mob yog cov kab mob yuav tsum tau tshwm sim los ntawm kev ua kom lawv tus tswv tsev; whereas worms yog stand-alone siab phem cov kev pab cuam uas muaj peev xwm nws tus kheej-replicate thiab propagate nws tus kheej sai li sai tau raws li lawv tau ua txhaum lub system
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
Qhov twg dotted kab yog ib txoj kab ntawm symmetry?
Cov kab dotted hauv nruab nrab ntawm tsab ntawv A, hauv qab no, yog hu ua daim iav kab, vim tias yog tias koj tso daim iav rau nws, qhov kev xav zoo li zoo ib yam li qhov qub. Lwm lub npe rau daim iav kab yog kab ntawm symmetry. Hom symmetry no kuj tseem hu ua reflective symmetry lossis reflection symmetry
