Qee zaum yuav tsum ua yam yooj yim, thiab nws hloov tawm tias peb tsis paub yuav ua li cas. Piv txwv li - yuav ua li cas kos ib lub rhombus. Nws yog qhov yooj yim heev.
Nyob rau hauv kab lus no koj yuav kawm yuav ua li cas kos lub rhombus kom raug, thiab dab tsi ntawm daim duab geometric nws yog.
Dab tsi yog pob zeb diamond?
Rhombus yog ib hom parallelogram, qhov peculiarity ntawm uas yog qhov opposite sab ntawm daim duab no yog parallel rau ib leeg, thiab nyob rau hauv ib lub rhombus lawv kuj sib npaug zos rau ib leeg. Lub ntsiab lus ntawm lub rhombus mus rau daim ntawv dav dav ntawm parallelogram yog qhia los ntawm qhov tseeb tias cov ces kaum sib npaug sib npaug.
Yuav ua li cas kos pob zeb diamond
Muaj ntau txoj hauv kev los kos cov duab zoo li rhombus. Hauv kab lus no, peb yuav saib ob txoj hauv kev yooj yim.
Rau thawj txoj kev, peb xav tau: tus cwj mem lossis cwj mem, lub lwv, daim ntawv txheeb xyuas los ntawm lub tsev kawm ntawv phau ntawv, tus pas ntsuas, lossis ib yam khoom ncaj nraim zoo ib yam li nws, yog tias qhov ntev ntawm lub rhombus tsis tseem ceeb..
- Yog li, rau qhov pib, cia peb kos ib lub cim ntawm ib qho kev sib tshuam ntawm cov kab ntawm tes. Nws yog qhov zoo dua, ntawm chav kawm, tso lub ntsiab lus tsis dhau ze rau cov npoo. Kev txiav txim siab ntawm qhov ntau thiab tsawgshapes.
- Ntxiv mus los ntawm qhov nruab nrab, suav cov lej xav tau ntawm lub hlwb mus rau sab laug (lossis sab xis) thiab muab lwm qhov taw qhia. Nyob rau sab nraud, kos qhov thib peb los ntawm tib lub xov tooj ntawm tes. Tam sim no peb ua tib yam hauv kev taw qhia nce thiab nqis. Cov kab ke tsis muaj teeb meem, qhov tseem ceeb ntawm no yog suav qhov kev ncua deb ntawm qhov nruab nrab mus rau sab laug thiab sab xis thiab sib cais nce thiab nqis. Qhov ntawd yog, yog tias plaub lub hlwb raug suav rau sab xis, thiab rau lub hlwb raug suav, raws li, plaub lub hlwb raug suav rau sab laug, rau lub hlwb raug suav.
Txuas tag nrho cov ntsiab lus nrog tus pas ntsuas lossis lwm yam khoom tsim nyog, tshwj tsis yog rau nruab nrab. Lub ntsiab lus nruab nrab tuaj yeem raug tshem tawm nrog lub lwv yog tias koj siv xaum. Lub rhombus npaj tau
Txoj kev thib ob zoo ib yam li thawj zaug, tab sis peb yuav kos rau ntawm daim ntawv huv tsis muaj hlwb. Peb xav tau qhov no: mem hluav thiab / lossis cwj mem, lub lwv, ib daim ntawv dawb huv, tus pas ntsuas thiab square (los yog ib qho khoom nrog lub kaum sab xis).
- Xaiv qhov loj. Kos ib lub dot.
- Coj tus pas ntsuas, muab taw tes rau ntawm qhov xav tau deb ntawm qhov nruab nrab ntawm sab laug. Peb txuas lawv nrog ib tug cwj mem kom cov kab hla mus rau qhov nruab nrab taw tes. Peb ua tej yam zoo sib xws nyob rau hauv qhov opposite direction.
- Kuj kos ib lub cim rau saum thiab hauv qab, tab sis siv ib lub xwmfab los ua kab ntawm sab saum toj thiab hauv qab taw tes perpendicular rau kab ntawm sab laug thiab sab xis.
- Txhua cov dots ua ke. Rho tawm cov kab hauv nruab nrab ntawm daim duab nrog lub lwv.
