Hauv geometry, ob daim duab tau hais tias zoo sib xws yog tias lawv muaj (ib qho thiab) tib yam, tab sis tsis tas yuav tsum muaj qhov loj me. Lub cim "~" uas peb siv los qhia zoo sib xws yog vim tus German mathematician Gottfried Wilhelm Leibniz (1646-1716).

Tsis tas li ntawd, qhov zoo sib xws siv li cas hauv lub neej tiag tiag?

Kev siv ntawm zoo sib xws Daim duab peb sab yog qhov tseem ceeb tshaj plaws uas nws dhau ntawm peb mus txog rau lub cev ntsuas qhov deb thiab qhov siab nrog cov cuab yeej ntsuas yooj yim. Kev txheeb xyuas cov duab ntxoov ntxoo uas ua cov duab peb sab peb tuaj yeem txiav txim siab qhov siab ntawm qhov khoom. Feem ntau siv txhawm rau txheeb xyuas kev ruaj ntseg ntawm cov choj.

Qhov thib ob, qhov zoo sib xws yog dab tsi? A zoo sib xws yog ib yam los yog alikeness. Thaum koj muab ob qho piv txwv - khoom siv lub cev, lub tswv yim, lossis kev paub - koj feem ntau saib lawv zoo sib xws thiab lawv qhov sib txawv. Qhov txawv yog qhov opposite ntawm zoo sib xws . Ob lub squares thiab duab plaub muaj plaub sab, uas yog a zoo sib xws nruab nrab ntawm lawv.

Ntxiv mus, lub ntsiab lus ntawm kev zoo sib xws hauv lej yog dab tsi?

Geometry. (ntawm cov duab) muaj cov duab zoo ib yam; muaj cov sab proportional thiab coj cov ces kaum sib npaug: zoo sib xws daim duab peb sab. lej . (ntawm ob square matrices) ntsig txog los ntawm txhais tau tias ntawm a zoo sib xws kev hloov pauv.

Muaj pes tsawg hom kev zoo sib xws?

Muaj plaub zoo sib xws xeem rau daim duab peb sab. Yog tias ob lub kaum sab xis ntawm ib daim duab peb sab sib npaug rau ob lub kaum sab xis ntawm lwm daim duab peb sab, ces ob daim duab peb sab zoo sib xws.
