A kab segment yog a ib feem ntawm kab uas muaj ob txhais cov ntsiab lus kawg . A kab ntu nruab nrab yog ib phau ntawm cov ntsiab lus nyob rau hauv lub cov ntsiab lus kawg thiab nws muaj npe los ntawm nws cov ntsiab lus kawg . Ib ray is a kab uas tsuas muaj ib tug txhais kawg thiab ib sab uas extends endlessly deb ntawm lub qhov kawg.
Ib yam li ntawd, qhov ncaj yog ib feem ntawm kab thiab 2 qhov kawg?
A kab ntu muaj ob cov ntsiab lus kawg thiab ray muaj ib tug qhov kawg . yog li nws yog a kab ntu.
Qhov thib ob, pes tsawg qhov kawg ntawm ib ntu muaj? ob qhov kawg
Ua kom pom qhov no, puas yog ib feem ntawm kab ntawm ob qhov kawg?
A kab ntu yog ib feem ntawm kab ntawm ob qhov kawg.
Ib kab thiab kab ntu yog dab tsi?
Hauv geometry, a kab ntu yog ib feem ntawm a kab uas yog bounded los ntawm ob qhov kawg cov ntsiab lus, thiab muaj txhua lub ntsiab lus ntawm lub kab nruab nrab ntawm nws qhov kawg. Ib kaw kab ntu suav nrog ob qho kawg, thaum qhib kab ntu cais ob qhov kawg; ib nrab qhib kab ntu suav nrog raws nraim ib qho ntawm qhov kawg.
