Nov yog ob txoj hauv kev:
- Yog hais tias ob lub disjoint khub ntawm ob sab sib law liag ntawm ib tug quadrilateral yog congruent, ces nws yog ib tug kite (rov qab los ntawm kite txhais).
- Yog hais tias ib qho ntawm cov kab pheeb ces kaum ntawm lub quadrilateral yog lub perpendicular bisector ntawm lwm tus, ces nws yog kite (converse of a property).
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog tus yam ntxwv ntawm kite?
Kite cov khoom muaj xws li (1) ob khub sib law liag, congruent sab, (2) congruent non-vertex ces kaum thiab (3) perpendicular diagonals. Lwm yam tseem ceeb polygon cov khoom kom paub txog suav nrog cov khoom trapezoid, parallelogram zog, rhombus cov khoom, thiab cov duab plaub thiab square.
Kuj Paub, yog ib daim duab plaub perpendicular? Raws li koj tuaj yeem pom los ntawm cov duab mus rau sab laug, lub diagonals ntawm a duab plaub tsis txhob hla lub kaum sab xis (lawv tsis yog perpendicular ). (Tsuas yog cov duab plaub yog ib lub square.) Thiab cov ces kaum tsim los ntawm kev sib tshuam tsis yog ib txwm ntsuas tib yam (qhov loj me). Cov kaum sab hauv nruab nrab yog qhov loj tib yam (lawv yog congruent.)
Tom qab ntawd, lo lus nug yog, yog lub kite perpendicular?
DEFINITION: A kite yog quadrilateral uas plaub sab yog kos xws li muaj ob qhov sib txawv ntawm cov nyob ib sab, kev sib haum xeeb sab. THEOREM: Yog hais tias ib tug quadrilateral yog kite , diagonals yog perpendicular . THEOREM: Yog hais tias ib tug quadrilateral yog kite , nws muaj ib khub ntawm opposite ces kaum kev sib haum xeeb.
Ib daim duab plaub puas yog parallelogram?
A duab plaub muaj ob khub ntawm opposite sab parallel, thiab plaub txoj cai kaum. Nws kuj yog ib parallelogram , raws li nws muaj ob khub ntawm parallel sab.

Koj ua pov thawj li cas cov kab yog sib npaug hauv cov ntawv pov thawj?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Vim li cas txoj kev sib koom tes sib koom ua ke tseem ceeb?
Kev kawm Interdisciplinary tso cai rau kev sib txuas ntawm cov tswv yim thiab kev sib txuas ntawm cov yam ntxwv los ntawm ntau yam kev qhuab qhia. Nyob rau tib lub sijhawm nws hais txog cov tub ntxhais kawm qhov sib txawv ntawm tus kheej thiab pab tsim cov txuj ci tseem ceeb, hloov pauv tau
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
Dab tsi pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?
Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Yuav ua li cas koj tsim ib lub dav hlau sib koom ua ke hauv geometry?
Txhawm rau tsim ib lub dav hlau sib koom ua ke, peb ua raws li cov kauj ruam no: Kos ob kab kab sib txuas rau ib leeg, sib tshuam ntawm qhov taw tes 0 ntawm ob kab. Sau tus lej kab rov tav raws li x-axis thiab sau cov kab ntsug tus lej raws li y-axis
