Yog tias ob sab sib law liag ntawm a parallelogram yog congruent, ces nws yog ib rhombus (tsis yog qhov thim rov qab ntawm lub ntsiab lus lossis kev sib tham ntawm cov cuab yeej). Yog hais tias tus kab pheeb ces kaum ntawm a parallelogram bisects ob lub ces kaum, ces nws yog ib rhombus (tsis yog qhov thim rov qab ntawm lub ntsiab lus lossis kev sib tham ntawm cov cuab yeej).
Ua li no, ua li cas koj ua pov thawj ib yam dab tsi yog rhombus?
Rau ua pov thawj quadrilateral yog a rhombus , ntawm no yog peb txoj hauv kev: 1) Qhia tias cov duab yog a parallelogram nrog sib npaug ntev sab; 2) Qhia tias cov duab kab pheeb ces kaum yog txhua tus 'perpendicular bisectors; los yog 3) Qhia tias cov duab kab pheeb ces kaum bisect ob khub ntawm opposite ces kaum.
Kuj Paub, puas muaj tseeb tias txhua qhov parallelogram yog rhombus? Hauv ib parallelogram , cov opposite sab yog sib npaug whereas nyob rau hauv a rhombus tag nrho plaub sab yog sib npaug. Hauv ib parallelogram , lub diagonals bisect ib leeg whereas nyob rau hauv a rhombus lawv tsis sib ceg. Hauv ib rhombus , cov kab pheeb ces kaum sib cuam tshuam ib leeg ntawm txoj cai kaum thiab li no yog perpendicular rau ib leeg.
Ib yam li ntawd, koj ua pov thawj li cas tias lub parallelogram yog square?
Yog hais tias lub quadrilateral muaj plaub qhov sib koom ua ke thiab plaub lub kaum sab xis, ces nws yog a square (rov qab los ntawm square txhais). Yog tias ob sab sib law liag ntawm ib daim duab plaub yog congruent, ces nws yog a square (tsis yog qhov thim rov qab ntawm lub ntsiab lus lossis kev sib tham ntawm cov cuab yeej).
Puas yog rhombus diagonals perpendicular?
Properties ntawm a Rhombus Cov kab pheeb ces kaum yog perpendicular thiab sib pab. Cov ces kaum uas nyob ib sab yog ntxiv (Piv txwv li., ∠A + ∠B = 180°). A rhombus yog a parallelogram nws kab pheeb ces kaum yog perpendicular rau ib leeg.

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
Koj ua pov thawj li cas ib yam dab tsi yog lub hauv paus?
VIDEO Kuj nug, dab tsi ua rau lub hauv paus? Hauv kev ua lej, teeb B ntawm cov ntsiab lus (vectors) hauv vector space V hu ua a hauv paus , yog tias txhua lub ntsiab lus ntawm V tuaj yeem sau rau hauv ib txoj kev tshwj xeeb raws li ib qho (finite) linear ua ke ntawm cov ntsiab lus ntawm B.

Koj ua pov thawj li cas ntawm cov ces kaum sab nrauv ntawm daim duab peb sab yog 360?
Lub kaum sab nrauv ntawm daim duab peb sab yog sib npaug rau qhov sib npaug ntawm cov kaum sab hauv sab nraud. Yog xav paub ntxiv txog qhov no saib Daim duab peb sab sab nraud lub kaum sab xis theorem. Yog tias lub kaum sib npaug raug coj los ntawm txhua qhov vertex, cov ces kaum sab nrauv ib txwm ntxiv rau 360 ° Qhov tseeb, qhov no muaj tseeb rau txhua qhov convex polygon, tsis yog daim duab peb sab
Koj ua pov thawj li cas tias ob ntu yog sib haum?
Cov ntu sib txuas yog cov kab kab uas sib npaug ntawm qhov ntev. Congruent txhais tias sib npaug. Cov kab sib txuas feem ntau yog qhia los ntawm kev kos tib tus nqi ntawm cov kab me me nyob rau hauv nruab nrab ntawm cov ntu, nyob rau ntawm ntu. Peb qhia ib kab los ntawm kos ib kab hla nws ob qhov kawg
