Cov ntawv zoo li B thiab D muaj kab rov tav kab ntawm symmetry : lawv qhov saum thiab hauv qab sib phim. Ib txhia ntawv Piv txwv li, X, H, thiab O, muaj ob qho tib si ntsug thiab kab rov tav kab ntawm symmetry . Thiab qee qhov, zoo li P, R, thiab N , muaj tsis muaj kab ntawm symmetry.
Yog li ntawd, tsab ntawv kuv puas muaj kab ntawm symmetry?
J, K, L, N, thiab P muaj xoom kab ntawm symmetry . M muaj ib kab ntawm symmetry , thiab H, Kuv, thiab O muaj 2 kab ntawm symmetry . Q, R, S tsis yog symmetrical , yog li ntawd lawv muaj xoom kab ntawm symmetry . T, U, thiab V yog symmetrical , tab sis lawv txhua tus muaj ib leeg xwb kab ntawm symmetry.
Ib tug kuj yuav nug, pes tsawg tus tsiaj ntawv ntawm cov tsiaj ntawv Askiv tsis sib haum xeeb txog ib kab? Yog kuv to taub point symmetry yog lawm ces O thiab tejzaum X yog tus xwb ntawv uas muaj ob lub ntsiab lus thiab kab symmetry . Qhov no yuav tawm F, G, J, K, L, N, P, Q, R, S, thiab Z, rau tag nrho 11 ntawv , uas tsis muaj qhov taw tes lossis kab symmetry.
Ua raws li qhov kev pom no, tsab ntawv C puas muaj kab ntawm symmetry?
B, C , D, E thiab K muaj kab rov tav kab ntawm symmetry . Ob leeg kab rov tav thiab ntsug kab ntawm symmetry tshwm sim hauv H, I thiab X. Meanwhile, F, G, J, L, N, P, Q, R, S thiab Z muaj tsis muaj kab ntawm symmetry.
Tus lej twg muaj kab ntawm symmetry?
0 muaj ob kab ntawm symmetry (ntsug thiab kab rov tav), ntxiv rau 180 degree rotational 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
Koj puas tuaj yeem kos ib daim duab peb sab uas muaj ib kab ntawm symmetry?
(a) Yog, peb tuaj yeem kos ib daim duab peb sab isosceles uas tsuas muaj 1 kab ntawm symmetry
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
Puas muaj ib txoj hauv kev pov tseg qhov kev kuaj xyuas los ntawm txoj kev uas tsis muaj cov lus pov tseg?
9 Teb. Koj tuaj yeem pov cov kev txwv tsis raug txheeb xyuas yam tsis tas yuav tshaj tawm lawv yog tias koj xav tau tiag tiag. Unchecked kev zam txuas ntxiv RuntimeException. Throwables uas txuas ntxiv yuam kev tseem tsis tau txheeb xyuas, tab sis tsuas yog yuav tsum tau siv rau cov teeb meem loj tiag tiag (xws li invalid bytecode)
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
