Skew kab yog ob lossis ntau txoj kab uas tsis sib tshuam, tsis sib npaug, thiab tsis yog coplanar(Nco ntsoov cov kab sib txuas thiab kab sib tshuam yog nyob ntawm tib lub dav hlau.) Qhov no ua rau cov kab skew tshwj xeeb - koj tuaj yeem pom cov kab skew hauv cov duab nrog peb lossis ntau qhov ntev.
Yuav ua li cas koj thiaj paub tias kab yog skew?
Ib qho piv txwv yooj yooj yim ntawm ib khub kab skew yog ob kab ntawm tawm tsamntawm ib txwm tetrahedron. Ob kab uas ob leeg pw hauv tib lub dav hlau yuav tsum hla ib leeg los yog sib npaug, yog li skew kab tuaj yeem muaj nyob hauv peb lossis ntau qhov ntev. Ob kab yog skew yog thiab tsuas yog tias lawv tsis yog coplanar.
txhais li cas yog ntu yog skew?
Hauv Geometry, skew ntu yog ntu ntawm cov kab skew, qhov skew kab yog cov kab uas tsis nyob ntawm tib lub dav hlau, thiab lawv kuj tsis sib tshuam.
Dab tsi yog kab skew nrog piv txwv?
Skew kab yog cov kab ncaj nraim hauv peb daim ntawv uas tsis sib luag thiab tsis hla. Ib qho piv txwv ntawm skew kab yog txoj kev taug kev nyob rau hauv pem hauv ntej ntawm lub tsev thiab ib txoj kab khiav hla sab saum toj ntawm ib sab ntawm ib lub tsevCov kab ncaj nraim uas tsis nyob hauv tib lub dav hlau thiab tsis sib tshuam.
Yuav ua li cas koj thiaj paub yog tias ob kab sib npaug lossis skew?
parallel yog tias qhov sib npaug sib npaug yog qhov tseeb kev sib tshuam yog cov kab tsis sib npaug lossis yog tias koj tuaj yeem daws tau lawv raws li kev sib npaug sib npaug. perpendicular yog cov kab sib tshuam thiab lawv cov khoom dot yog 0. skew yog cov kab tsis sib luag thiab tsis sib tshuam.
