CPCTC feem ntau yog siv los yog ze rau qhov kawg ntawm cov pov thawj uas hais kom tus menyuam kawm ntawv qhia tias ob lub kaum sab xis lossis ob sab yog qhov sib haum. Nws txhais tau hais tias ib zaug ob daim duab peb sab tau ua pov thawj tias muaj kev sib haum xeeb, ces peb khub ntawm sab uas sib haum yuav tsum sib haum thiab peb lub kaum sab xis uas sib haum yuav tsum sib haum.
Hais txog qhov no, Cpcfc txhais li cas?
Qhov sib thooj ntawm cov duab sib dhos yog sib haum
Tsis tas li ntawd, Cpctc yog dab tsi thiab piv txwv? Qhov sib thooj ntawm cov duab peb sab yog qhov sib txuam Nws txhais tau hais tias yog tias ob lub trangles paub tias muaj kev sib haum xeeb, ces tag nrho cov kaum sab xis / sab sib txuas kuj sib haum. Raws li ib piv txwv , yog tias 2 daim duab peb sab sib dhos los ntawm SSS, ces peb kuj paub tias cov ces kaum ntawm 2 daim duab peb sab yog congruent.
Tom qab ntawd, lo lus nug yog, Cpctc yog qhov theorem?
1 Teb. Nws yog ib theorem uas tam sim ntawd ua raws los ntawm lub ntsiab lus ntawm congruence (nyob ntawm seb lub ntsiab lus koj siv), Los ntawm Wikipedia: "Ob daim duab peb sab yog congruent yog hais tias lawv sib raug sab yog sib npaug zos nyob rau hauv ntev thiab lawv cov ces kaum sib npaug zos loj."
Cpctc Theorem yog dab tsi?
CPCTC yog ib tug acronym rau coj qhov chaw ntawm congruent triangles yog congruent. CPCTC feem ntau yog siv los yog ze rau qhov kawg ntawm ib qho pov thawj uas hais kom tus menyuam kawm ntawv qhia tias ob lub kaum sab xis lossis ob sab yog qhov sib haum. Qhov sib thooj txhais tau tias lawv nyob hauv tib txoj hauj lwm hauv 2 daim duab peb sab.
