Lub alternate interior Angles Theorem hais tias, thaum ob kab sib luag raug txiav los ntawm kev hloov pauv, qhov tshwm sim ntawm cov ces kaum sab hauv yog sib haum.
Puas yog cov kaum sab hauv hloov pauv ib txwm sib haum?
Tsuas muaj ib khub ntawm kev hloov sab hauv lub kaum sab xis thiab lub kaum sab xis 3 thiab nws sab nraud nyob nruab nrab ntawm cov kab sib txuas uas yog 5. Yog li hloov sab hauv cov ces kaum yuav ib txwm sib haumthiab ib txwm nyob ntawm qhov sib txawv ntawm qhov kev hloov pauv no.
Koj ua li cas ua pov thawj tias cov kaum sab nrauv sab nrauv yog sib haum?
Lwm cov ces kaum sab nrauv yog congruent yog cov kab hla los ntawm kev hloov pauv yog sib npaug. Yog hais tias qhov sib txawv sab nrauv cov ces kaum yog congruent, ces cov kab yog parallel. Ntawm txhua qhov kev sib tshuam, cov ces kaum sib thooj nyob ntawm tib qhov chaw.
Puas yog lwm cov kaum sab hauv ntxiv?
Yes alternate interior angles are supplementary.
Cov piv txwv sab hauv sab hauv yog dab tsi?
Ua raws li qhov hloov pauv sab hauv lub theorem, yog tias ob txoj kev sib luag, thiab Maple Avenue raug suav tias yog qhov kev hloov pauv, ces x thiab 40 ° yog qhov hloov sab hauv lub kaum sab xis. Yog li ntawd, ob lub kaum sab xis yog sib npaug. Yog li ntawd, x=40 °. Txhua khub ntawm cov ces kaum sab hauv yog sib npaug.
