Nco ntsoov tias kab skew yog kab uas tsis nyob ntawm tib lub dav hlau, tsis txhob sib tshuam, lossis sib npaug. Qhov no txhais tau hais tias skew kab yeej tsis coplanar thiab hloov yog noncoplanar.
Puas skew kab qee zaum coplanar?
kab kab yog ob lossis ntau kab uas tsis sib tshuam, tsis sib luag, thiab tsis yog coplanar. (Nco ntsoov tias cov kab sib npaug thiab cov kab sib tshuam yog nyob rau tib lub dav hlau.) … Txij li cov kab ntawm txhua qhov chaw nyob hauv cov dav hlau sib txawv, cov kab hauv txhua qhov chaw yuav tsis sib ntsib, thiab lawv yuav tsis sib npaug.
Puas skew kab congruent?
Skew kab yog kab uas tsis yog-coplanar (lawv tsis nyob hauv tib lub dav hlau) thiab tsis sib tshuam. Skew kab sib txawv _ thiab yeej tsis _.
Puas yog tag nrho cov kab uas tsis yog kab sib npaug?
Ob kab yog kab sib npaug yog tias lawv yog coplanar thiab tsis sib tshuam. Kab uas tsis yog coplanar thiab tsis sib tshuam yog hu ua skew kab. Ob lub dav hlau uas tsis sib tshuam yog hu ua cov dav hlau sib luag.
Puas skew kab yog kab pheeb ces kaum?
kab pheeb ces kaum. Txij li cov kab skew yuav tsum muaj hauv qhov chaw peb sab, koj tuaj yeem suav nrog kab pheeb ces kaum hauv koj qhov kev tshawb nrhiav kab skew. Ib txoj kab txiav diagonally ntawm ib ces kaum ntawm lub elevator lub qab nthab mus rau lwm lub ces kaum ntawm tib lub qab nthab yog skew mus rau plaub ntug ntawm pem teb.
