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.
