Tag nrho cov rhombuses yog parallelograms , tab sis tsis yog tag nrho parallelograms yog rhombuses . Txhua squares yog rhombuses , tab sis tsis yog tag nrho cov rhombuses yog squares. Lub opposite sab hauv cov ces kaum ntawm rhombuses yog concruent. Diagonals ntawm a rhombus ib txwm sib cais ib leeg ntawm txoj cai kaum.

Yog li, puas yog rhombus ib txwm muaj cov duab sib dhos?

Yog tias cov duab nyob hauv qab lwm qhov, ces nws yog ib txwm cov duab saum nws thiab Yog li a rhombus yog ib txwm parallelogram , ib square ib txwm ib lub duab plaub, thiab ib txwm muaj cov duab sib dhos , thiab ib txwm quadrilateral, thiab lwm yam.

Ib tug kuj yuav nug, yog vim li cas txhua rhombus yog parallelogram tab sis tsis yog txhua parallelogram ib tug rhombus? Ob leeg parallelogram thiab rhombus yog quadrilateral , uas tig sab yog parallel, cov ces kaum sib txawv yog sib npaug, qhov sib npaug ntawm cov kaum sab hauv yog 360 degree. A rhombus nws tus kheej yog hom tshwj xeeb ntawm parallelogram . Yog li ntawd, nws tuaj yeem hais tau tias txhua rhombus yog a parallelogram , tab sis rov qab yog tsis yog ua tau.

Hais txog qhov no, puas yog parallelogram ib lub rhombus muaj lossis tsis?

Yog lawm , a rhombus yog quadrilateral nrog 4 sab sib npaug. Txhua square muaj 4 qhov sib npaug ntawm sab, yog li txhua square yog a rhombus . A parallelogram yog quadrilateral nrog 2 khub ntawm parallel sab. Ob sab ntxeev rau txhua square yog parallel, yog li txhua square yog a parallelogram.

Puas yog tag nrho cov squares parallelograms?

Ib square yog ib parallelogram . Qhov no yeej ib txwm muaj tseeb. Squares yog quadrilaterals nrog 4 congruent sab thiab 4 txoj cai kaum, thiab lawv kuj muaj ob pawg ntawm parallel sab. Txij thaum squares yuav tsum yog quadrilaterals nrog ob pawg ntawm parallel sab, ces txhua lub xwmfab yog parallelograms.
