A rhombus muaj tag nrho cov khoom ntawm a parallelogram : Ob leeg ntawm opposite sab yog thaum uas tig mus . Ob leeg ntawm opposite sab yog sib npaug nyob rau hauv ntev. Ob khub ntawm opposite cov ces kaum yog sib npaug.
Tsis tas li ntawd, ob qho tib si ntawm ob tog sib npaug sib luag hauv ib qho parallelogram?
DEFINITION: A parallelogram yog quadrilateral nrog ob khub ntawm opposite sab parallel . THEOREM: Yog hais tias lub quadrilateral yog a parallelogram , nws muaj 2 sets ntxeev sab kev sib haum xeeb. THEOREM: Yog hais tias lub quadrilateral muaj cov ces kaum sib law liag uas yog supplementary, ces nws yog a parallelogram.
Ib yam li ntawd, lub quadrilateral yog dab tsi nrog ib khub ntawm opposite sab uas yog parallel? trapezoid
Tsis tas li ntawd, puas yog lub rhombus muaj qhov sib txawv ntawm qhov sib npaug?
A Rhombus yog ib lub tiaj tus nrog 4 sib npaug ncaj sab . Sab nraud yog thaum uas tig mus , thiab rov qab cov ces kaum yog sib npaug (nws yog Parallelogram). Thiab cov kab pheeb ces kaum "p" thiab "q" ntawm a rhombus bisect ib leeg ntawm txoj cai kaum.
Yuav ua li cas muaj pes tsawg leeg ntawm ib lub rhombus?
Txhua rhombus muaj ob lub diagonals txuas khub ntawm opposite vertices, thiab ob khub ntawm parallel sab.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
