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
