Dab tsi yog parallel intersecting thiab perpendicular kab ? A. Parallel kab yog kab nyob rau hauv ib lub dav hlau uas ib txwm sib nrug deb. Perpendicular kab yog kab uas sib tshuam ntawm lub kaum sab xis (90 degrees).

Kuj tseem paub, dab tsi yog cov kab sib tshuam perpendicular?

Hauv geometry, ib ceg ntawm kev ua lej, kab perpendicular raug txhais ua ob kab uas ntsib los yog sib tshuam ib leeg ntawm lub kaum sab xis (90 °).

Kuj Paub, kab kab perpendicular yog dab tsi? Hauv elementary geometry, cov cuab yeej ntawm kev ua perpendicular (perpendicularity) yog kev sib raug zoo ntawm ob kab uas sib ntsib ntawm lub kaum sab xis (90 degrees). Cov cuab yeej txuas mus rau lwm yam khoom siv geometric. A kab yog hais tias yog perpendicular rau lwm tus kab yog ob tug kab sib tshuam ntawm lub kaum sab xis.

Tsis tas li lo lus nug yog, ob kab ntawm cov kab tuaj yeem ua rau tib lub sijhawm thiab perpendicular?

Tsis txhob. kab sib npaug txhais tau tias lawv yuav tsum sib tshuam thiab perpendicular txhais tau tias lawv yuav tsum sib tshuam ntawm 90 degrees. cov 2 no tsis tuaj yeem tshwm sim tib lub sijhawm.

Lub cim rau perpendicular yog dab tsi?

Ob kab uas sib tshuam thiab tsim cov kaum sab xis yog hu ua perpendicular kab. Cov cim ⊥ yog siv los qhia perpendicular kab. Hauv daim duab, kab l ⊥ kab m.
