Diagonals ntawm a rhombus

Hauv ib qho twg rhombus , cov kab pheeb ces kaum (kab txuas cov ces kaum sib txawv) sib sib zog nqus ntawm txoj cai kaum (90 °). Ntawd yog, txhua tus kab pheeb ces kaum txiav rau lwm qhov rau hauv ob qhov sib npaug, thiab lub kaum sab xis uas lawv hla yog ib txwm 90 degrees.

Yog li ntawd, cov diagonals ntawm ib lub rhombus sib npaug?

Cov diagonals ntawm rhombus sib sib. Qhov no txhais tau hais tias lawv txiav ib leeg ib nrab. Yog li ntawd, kab pheeb ces kaum ua sib npaug yog ib rooj plaub tshwj xeeb thaum txhua sab ntawm lub rhombus yog sib npaug i.e yog square.

Tsis tas li ntawd, cov khoom ntawm rhombus yog dab tsi? Isotoxal daim duab Convex polygon

Tsis tas li ntawd, cov kab pheeb ces kaum puas sib haum xeeb hauv lub rhombus?

Tag nrho cov khoom ntawm a rhombus siv (cov uas tseem ceeb ntawm no yog cov sib npaug sab, kab pheeb ces kaum yog perpendicular bisectors ntawm ib leeg, thiab kab pheeb ces kaum bisect cov ces kaum). Tag nrho cov khoom ntawm daim duab plaub siv tau (tsuas yog ib qho tseem ceeb ntawm no yog kab pheeb ces kaum yog kev sib haum xeeb ). Txhua sab yog kev sib haum xeeb los ntawm txhais.

Koj pom kab pheeb ces kaum li cas?

Dab tsi yog qhov kab pheeb ces kaum Kev ntsuas ntawm ib daim duab plaub 150 ko taw ntev los ntawm 100 ko taw dav? Siv Pythagorean Theorem (a^2 + b^2 = c^2). A thiab B yog qhov ntev ntawm ob sab ntawm daim duab plaub. Yuav kom tau txais qhov ntev ntawm hypotenuse, koj yuav tsum tau daws rau C. C yog lub hauv paus square ntawm (A squared plus B squared).
