Ua li no, pes tsawg lub kaum sib npaug hauv lub rhombus?

A rhombus muaj plaub sab ntawm sib npaug ntev. Nws muaj ob khub ntawm sib npaug kaum . Lub opposite sab yog parallel. Cov diagonals bisect ib leeg ntawm txoj cai lub kaum sab xis.

Tsis tas li ntawd, lub rhombus puas muaj 4 lub kaum sib npaug? Rhombus . A Rhombus yog ib lub tiaj tus le4 sib ncaj sab. Sab nraud yog thaum uas tig mus , thiab opposite cov ces kaum sib npaug (nws yog Parallelogram). Thiab diagonals "p" thiab "q" ntawm a rhombus bisect sib at txoj cai kaum.

Tsis tas li ntawd, txhua sab sib npaug hauv rhombus?

A rhombus yog plaub-sided duab qhov twg txhua sab muaj sib npaug ntev (cim "s"). Kuj ntxeev sab yog thaum uas tig mus thiab rov qab cov ces kaum yog sib npaug . Lwm qhov nthuav yog tias cov kab pheeb ces kaum (dashed kab) sib ntsib hauv nruab nrab ntawm lub kaum sab xis. Hauv lwm lo lus lawv "bisect" (txiav hauv ib nrab) ib leeg ntawm txoj cai kaum.

Lub rhombus ntxiv rau dab tsi?

cov diagonals ntawm a rhombus bisect cov ces kaum vim hais tias ob sab yog congruent raws li lawv nyob rau hauv ib tug square. Plaub sab ntawm a rhombus yog sib npaug. Qhov no kuj txhais tau hais tias opposite ces kaum ntawm a rhombus muaj kev ntsuas sib npaug. Cov kaum sab hauv ntxiv rau 360 vim muaj plaub sab.
