Lub centroid ntawm lub mis trapezoid pab hauv kev xam qhov chaw ntawm lub centroid ntawm lub trapezoid. Lub trapezoid yog ib lub quadrilateral nrog ob sab sib npaug. Lub centroid ntawm lub trapezoid nyob nruab nrab ntawm ob lub hauv paus.
qhov chaw nruab nrab ntawm huab hwm coj ntawm lub trapezoid nyob qhov twg?
Qhov nruab nrab ntawm thaj chaw (qhov nruab nrab ntawm qhov loj rau lub teeb lamina) lies raws li txoj kab koom nrog qhov nruab nrab ntawm qhov sib luag, ntawm qhov kev ncua deb x ntawm sab ntev uas tuaj yeem xam los ntawm lub hauv paus thiab qhov siab ntawm lub trapezoid.
Centroid xam li cas?
Tom qab ntawd, peb tuaj yeem suav qhov nruab nrab ntawm daim duab peb sab los ntawm kev siv qhov nruab nrab ntawm x qhov chaw thiab y qhov chaw ntawm tag nrho peb qhov vertices. Yog li, cov mis centroid tuaj yeem ua lej raws li G(x, y)=((x1 + x2 + x3)/3, (y1 + y2 + y3)/3).
Yuav ua li cas siv mis rau lub trapezoid?
Ob lub qauv trapezoid yooj yim yog: Ib puag ncig ntawm Trapezoid yog qhov suav ntawm txhua sab. Qhia ua P=a + b + c + d. Qhov twg, a, b, c, thiab d yog ob sab ntawm lub trapezoid.
Vim li cas thaj tsam 1 2h b1 b2?
Ob sab sib npaug ntawm lub trapezoid yog nws lub hauv paus. Yog tias peb hu rau sab ntev b1 thiab sab luv b2, ces lub hauv paus ntawm parallelogram yog b1 + b2. luas=1 2 (base 1 + base 2)(height). A=1 2 h(b1 + b2) Thaj tsam ntawm a trapezoid yog ib nrab ntawm nws qhov siabmultiplied los ntawm cov lej ntawm nws ob lub hauv paus.
