Yog tias ob sab sib law liag ntawm a parallelogram yog congruent, ces nws yog ib rhombus (tsis yog qhov thim rov qab ntawm lub ntsiab lus lossis kev sib tham ntawm cov cuab yeej). Yog hais tias tus kab pheeb ces kaum ntawm a parallelogram bisects ob lub ces kaum, ces nws yog ib rhombus (tsis yog qhov thim rov qab ntawm lub ntsiab lus lossis kev sib tham ntawm cov cuab yeej).

Ua li no, ua li cas koj ua pov thawj ib yam dab tsi yog rhombus?

Rau ua pov thawj quadrilateral yog a rhombus , ntawm no yog peb txoj hauv kev: 1) Qhia tias cov duab yog a parallelogram nrog sib npaug ntev sab; 2) Qhia tias cov duab kab pheeb ces kaum yog txhua tus 'perpendicular bisectors; los yog 3) Qhia tias cov duab kab pheeb ces kaum bisect ob khub ntawm opposite ces kaum.

Kuj Paub, puas muaj tseeb tias txhua qhov parallelogram yog rhombus? Hauv ib parallelogram , cov opposite sab yog sib npaug whereas nyob rau hauv a rhombus tag nrho plaub sab yog sib npaug. Hauv ib parallelogram , lub diagonals bisect ib leeg whereas nyob rau hauv a rhombus lawv tsis sib ceg. Hauv ib rhombus , cov kab pheeb ces kaum sib cuam tshuam ib leeg ntawm txoj cai kaum thiab li no yog perpendicular rau ib leeg.

Ib yam li ntawd, koj ua pov thawj li cas tias lub parallelogram yog square?

Yog hais tias lub quadrilateral muaj plaub qhov sib koom ua ke thiab plaub lub kaum sab xis, ces nws yog a square (rov qab los ntawm square txhais). Yog tias ob sab sib law liag ntawm ib daim duab plaub yog congruent, ces nws yog a square (tsis yog qhov thim rov qab ntawm lub ntsiab lus lossis kev sib tham ntawm cov cuab yeej).

Puas yog rhombus diagonals perpendicular?

Properties ntawm a Rhombus Cov kab pheeb ces kaum yog perpendicular thiab sib pab. Cov ces kaum uas nyob ib sab yog ntxiv (Piv txwv li., ∠A + ∠B = 180°). A rhombus yog a parallelogram nws kab pheeb ces kaum yog perpendicular rau ib leeg.
