Cov kab pheeb ces kaum ntawm a square bisect nws cov ces kaum. Sab nraud ntawm a square yog ob qho tib si parallel thiab sib npaug nyob rau hauv ntev. Tag nrho plaub sab ntawm a square yog sib npaug . Cov kab pheeb ces kaum ntawm a square yog sib npaug.
Ib yam li ib tug yuav nug, puas yog diagonals ntawm daim duab plaub sib npaug?
A duab plaub yog ib tug parallelogram, yog li nws opposite sab sib npaug . Cov kab pheeb ces kaum ntawm a daim duab plaub yog sib npaug thiab sib cais.
tus qauv kab pheeb ces kaum yog dab tsi? Diagonal Formula . Txhua square uas muaj ob kab pheeb ces kaum sib npaug ntawm qhov ntev rau ib leeg. Diagonal Formula yog siv los xam cov polygon diagonals. Diagonals yog ib txoj kab uas txuas nrog ob qhov tsis nyob ib sab ntawm ib qho polygon piv txwv li a kab pheeb ces kaum koom nrog ob lub vertices ntawm lub polygon tsis suav nrog cov npoo ntawm daim duab.
Ib yam li ntawd, cov diagonals ntawm rhombus sib npaug?
Cov kab pheeb ces kaum ntawm a rhombus sib sib. Qhov no txhais tau hais tias lawv txiav ib leeg ib nrab. Yog li ntawd, kab pheeb ces kaum ua sib npaug yog ib rooj plaub tshwj xeeb thaum txhua sab ntawm lub rhombus yog sib npaug i.e yog square. Txwv tsis pub.
Puas yog cov kab pheeb ces kaum ntawm lub trapezium sib npaug?
Diagonals yog sib npaug tsuas yog nyob rau hauv cov ntaub ntawv tshwj xeeb ntawm trapezium hu ua trapezoid (los yog isosceles trapezium ). Nws yog ib tug yam ntxwv khoom ntawm trapezoid , uas kab pheeb ces kaum yog sib npaug . Nws tsis tsim nyog li ntawd kab pheeb ces kaum ntawm txhua hom trapezium yog sib npaug.
Pom zoo:
Puas yog qhov sib npaug ntawm ob lub polynomials ib txwm yog polynomial?
Qhov sib npaug ntawm ob lub polynomials yeej ib txwm yog polynomial, yog li qhov sib txawv ntawm ob polynomials kuj tseem yog ib qho polynomial
Kev sib cav sib ceg sib txawv li cas ntawm kev sib cav tsis zoo?
Txhua qhov kev sib cav tsis zoo siv txoj cai invalid inference. Yog tias qhov kev sib cav tsis zoo koj paub tias nws tsis siv. Kev siv tau txhais tau tias tsis muaj kev txhais lus qhov twg qhov chaw muaj tseeb thiab qhov kev txiav txim siab tuaj yeem tsis tseeb ib txhij. Yog tias qhov kev sib cav ua txhaum koj tuaj yeem tsis quav ntsej nws thiab sim nkag siab lub ntsiab lus tseem
Puas yog ob kab pheeb ces kaum ntawm parallelogram sib npaug?
Thaum ib qho parallelogram muab faib ua ob daim duab peb sab peb tau pom tias cov ces kaum thoob plaws ib sab (ntawm no kab pheeb ces kaum) sib npaug. Qhov no ua pov thawj tias cov kaum sab xis nyob rau hauv parallelogram kuj sib npaug. Cov kab pheeb ces kaum ntawm parallelogram tsis yog qhov sib npaug
Puas yog diagonals ntawm lub kaum sab xis square bisectors?
Lub square muaj cov khoom nram qab no: Tag nrho cov khoom ntawm lub rhombus siv (cov uas tseem ceeb ntawm no yog cov kab sib dhos, kab pheeb ces kaum yog perpendicular bisectors ntawm ib leeg, thiab diagonals bisect lub ces kaum). Tag nrho cov khoom ntawm daim duab plaub siv tau (tsuas yog ib qho tseem ceeb ntawm no yog kab pheeb ces kaum yog congruent)
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
