Thaum a parallelogram muab faib ua ob daim duab peb sab peb tau pom tias lub kaum sab xis hla ntawm sab (ntawm no kab pheeb ces kaum ) yog sib npaug . Qhov no ua pov thawj tias cov kaum sab nraud ntawm a parallelogram kuj yog sib npaug . Cov kab pheeb ces kaum ntawm a parallelogram tsis yog ntawm sib npaug ntev.

Nyob rau hauv no hais txog, uas parallelogram muaj sib npaug diagonals?

Hauv ib parallelogram , opposite sab yog sib npaug , opposite angles yog sib npaug thiab kab pheeb ces kaum sib sib. Hauv ib rhombus diagonals sib tshuam ntawm txoj cai kaum. Hauv ib daim duab plaub kab pheeb ces kaum yog sib npaug.

Tom qab ntawd, lo lus nug yog, puas yog 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.

Tsuas yog li ntawd, nyob rau hauv uas quadrilateral diagonals sib npaug?

Ib qho xwm txheej sib npaug yog tias cov sab nraud yog sib npaug (ib qho square yog parallelogram), uas yog kab pheeb ces kaum perpendicularly bisect ib leeg, thiab yog ntawm sib npaug ntev. A quadrilateral yog ib lub square yog thiab tsuas yog tias nws yog ob qho tib si rhombus thiab ib daim duab plaub (plaub sib npaug sab thiab plaub sib npaug cov ces kaum).

Puas yog diagonals sib npaug hauv trapezium?

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.
