A kab ntu muaj ob qhov kawg. Nws muaj cov ntsiab lus kawg no thiab tag nrho cov ntsiab lus ntawm cov kab nruab nrab lawv. Koj tuaj yeem ntsuas qhov ntev ntawm a ntu , tab sis tsis yog ib kab . A ray yog ib feem ntawm a kab uas muaj ib qho kawg thiab mus rau infinitely hauv tsuas yog ib qho kev taw qhia xwb.
Yog li ntawd, qhov txawv ntawm ntu thiab Rays yog dab tsi?
Ntu thiab rays A ntu yog ib feem ntawm kab uas muaj ob qhov kawg thiab muaj qhov ntev. Ntawm qhov tod tes, a ray kuj yog ib feem ntawm kab uas muaj ib qho kawg thiab lwm qhov kev taw qhia txuas ntxiv mus tsis kawg.
Ib sab saum toj no, dab tsi yog ib qho hluav taws xob hauv lej? Hauv geometry, a ray yog ib txoj kab nrog ib qho kawg (los yog taw tes ntawm lub hauv paus chiv keeb) uas txuas mus rau infinitely nyob rau hauv ib qho kev taw qhia.
Dab tsi yog qhov txawv ntawm kab thiab kab ntu?
Ntsiab Qhov sib txawv ntawm kab thiab kab ntu Hauv qab no yog ob peb yam sib txawv . Cov kab tsis muaj qhov kawg. Thaum lub kab ntu muaj ob qhov kawg. Raws li cov kab ntu muaj qhov pib thiab qhov kawg, nws txuas mus, nws tsis txuas rau ob qho tib si cov lus qhia.
Cov kab ntu zoo li cas?
A kab ntu yog sawv cev los ntawm cov ntsiab lus kawg ntawm txhua qhov kawg ntawm qhov kab ntu . A kab hauv geometry yog sawv cev los ntawm a kab nrog cov xub ntawm txhua qhov kawg. A kab ntu thiab a kab txawv vim a kab mus mus ib txhis thaum ib kab ntu muaj qhov pib thiab qhov kawg.
