Puas cov parallelograms muaj 90 degree kaum?
Ib qho Parallelogram tuaj yeem txhais tau tias yog quadrilateral uas nws ob sab yog tib yam rau ib leeg thiab tag nrho plaub lub kaum sab xis ntawm qhov vertices yog tsis yog 90 degrees lossis txoj caicov ces kaum, quadrilateral hu ua parallelogram. Cov sab nraud ntawm parallelogram kuj sib npaug ntawm qhov ntev.
Puas yog parallelogram muaj 4 lub kaum sib npaug?
Rectangle - Ib qho piv txwv nrog plaub lub kaum sib npaug ntawm qhov loj me (cov kaum sab xis). Rhombus - Ib qho parallelogram nrog plaub sab ntawm qhov sib npaug. Square - Ib qho parallelogram nrog plaub sab ntawm qhov sib npaug ntawm qhov ntev thiab cov ces kaum sib npaug (txoj cai kaum sab xis).
