Ib lub quadrilateral nrog cov kab rov tav kab sib dhos yog hu ua a parallelogram . Yog tias tsuas yog ib khub ntawm sab nraud yuav tsum tau ua kom sib luag, cov duab yog trapezoid. Lub trapezoid, nyob rau hauv uas tsis yog-parallel sab yog sib npaug ntawm qhov ntev, hu ua isosceles.
Yog li ntawd, dab tsi yog quadrilateral uas tsis muaj qhov sib luag hu ua?
Ib tug trapezoid ( hu ua lub trapezium nyob rau hauv UK) muaj ib khub ntawm opposite sab parallel . Thiab ib tug trapezium ( hu ua lub trapezoid nyob rau hauv UK) yog a quadrilateral nrog NO parallel sab : Trapezoid.
Qhov thib ob, 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 ib rhombus bisect ib leeg ntawm txoj cai kaum.
Ib yam li ntawd, puas yog tag nrho cov quadrilaterals muaj qhov sib npaug?
Trapezoids muaj tsuas yog ib khub ntawm parallel sab ; parallelograms muaj ob khub ntawm parallel sab . Ib tug trapezoid ua tau yeej tsis ua parallelogram. Trapezoids yog plaub-sided polygons, yog li lawv yog tag nrho cov quadrilaterals.
Puas yog Trapezium yog polygon?
A trapezium yog a polygon . Nws yog ib qho kaw, tiaj tus duab thiab nws ob sab yog ncaj. Nws yog quadrilateral, uas txhais tau hais tias nws muaj plaub sab. Qhov no txhais tau tias, raws li ib tug polygon , nws kuj muaj plaub lub kaum sab xis.

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
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
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
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
