1) Txhua plaub plaub fab muaj plaub lub kaum sab xis. 2) Tag nrho cov plaub hau plaub hau muaj qhov sib npaug. 3) Txhua quadrilaterals muaj plaub sab. 4) Tag nrho cov quadrilaterals yog parallelograms.
Yuav ua li cas yog ib txwm muaj tseeb ntawm plaub fab?
Nws muaj ob yam khoom ntawm quadrilaterals: A quadrilateral yuav tsum raug kaw nrog 4 sab . Txhua lub kaum sab hauv ntawm cov plaub fab sib npaug mus txog 360 °
Puas yog tag nrho cov quadrilaterals parallelograms Muaj tseeb lossis cuav?
Squares yog quadrilaterals nrog 4 congruent sab thiab 4 txoj cai ces kaum, thiab lawv kuj muaj ob pawg ntawm parallel sab. Parallelograms yog quadrilaterals nrog ob pawg ntawm kev sib luag. Txij li cov squares yuav tsum yog quadrilaterals nrog ob pawg ntawm qhov sib npaug, ces tag nrho cov squares yog parallelograms. Nov yog ib txwm muaj tseeb.
Dab tsi zoo piav qhia txog plaub fab?
Nyob rau hauv geometry, quadrilateral tuaj yeem txhais tau tias yog a kaw, ob sab duab uas muaj plaub sab ncaj. Lub polygon muaj plaub ntsug lossis kaum.
Koj paub dab tsi txog plaub npaug?
A quadrilateral yog a polygon uas muaj plaub sab. (Qhov no kuj txhais tau hais tias ib lub quadrilateral muaj raws nraim plaub vertices, thiab raws nraim plaub lub ces kaum.)
