Thaj chaw ntawm lub trapezoid yog pom siv tus qauv, A=½ (a + b) h, qhov twg 'a' thiab 'b' yog lub hauv paus (sib npaug sab) thiab 'h' yog qhov siab (qhov kev ncua deb ntawm lub hauv paus) ntawm lub trapezoid.
Vim li cas thaj tsam ntawm ib tug trapezoid b1 b2) H 2?
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) cheeb tsam ntawm ib tug trapezoid yog ib nrab ntawm nws qhov siab multiplied los ntawm cov sum ntawm nws ob lub hauv paus.
Vim li cas thaj tsam ntawm lub trapezoid?
Dissecting the trapezoid
Ob tug thaum uas tig mus yog lub hauv paus, thiab qhov siab, raws li ib txwm, yog qhov kev ncua deb ntawm ib lub hauv paus mus rau qhov opposite. Qhov chaw ntawm qhov parallelogram no yog nws qhov siab (ib nrab-qhov siab ntawm lub trapezoid) lub sij hawm nws lub hauv paus (sum ntawm lub hauv paus ntawm lub trapezoid), yog li nws cheeb tsam yog ib nrab-qhov siab × (base1 + base2).
Dab tsi yog qhov ib puag ncig ntawm lub trapezoid?
Lub cheeb tsam ntawm lub trapezoid yog qhov sib npaug ntawm qhov ntev ntawm nws plaub sab. Yog tias ib lossis ntau qhov ntev tsis paub, qee zaum koj tuaj yeem siv Pythagorean Theorem nrhiav nws.
thaj tsam ntawm isosceles trapezoid yog dab tsi?
Cov mis los xam thaj tsam ntawm ib qho isosceles trapezoid yog Area=(sum of parallel side ÷ 2) × qhov siab.

Kev piav qhia: Cov kab mob saphenous loj nyob hauv qis qis. Nws kuj tseem paub tias ntev saphenous leeg. Nws yog cov hlab ntsha loj tshaj plaws ntawm lub cev. Yawg saphenous leeg nyob qhov twg? Keeb kwm thiab kev kawm. Cov kab mob saphenous zoo nyob nyob rau hauv cov ntaub so ntswg subcutaneous ntawm ob txhais ceg hauv ncej puab hauv saphenous compartment , uas yog bounded posteriorly los ntawm qhov tob fascia thiab superficially los ntawm saphenous fascia 3.
Puas yog kev tawm tsam ntawm 1857 kev tawm tsam ntawm sepoys?

Thaj tsam frontoparietal ntawm lub hlwb nyob qhov twg?
cheeb tsam frontoparietal yog ib feem ntawm lub paj hlwb uas lub frontal thiab parietal lobes sib ntsib. thaj tsam frontoparietal ua dab tsi? Lub frontoparietal network yog a tswj network, txawv ntawm cov salience thiab cingulo-opercular tes hauj lwm, ua hauj lwm kom sai thiab instantiate tshiab hauj lwm xeev los ntawm flexibly interacting nrog rau lwm yam kev tswj thiab kev tes hauj lwm.
Yuav ua li cas thiaj nrhiav tau thaj tsam ntawm lub oval?
Multiply by pi. Thaj tsam ntawm lub ellipse yog a x b x π. Txij li thaum koj muab ob chav nyob ntawm qhov ntev ua ke, koj cov lus teb yuav nyob rau hauv units squared. Piv txwv li, yog ib lub vojvoog muaj ib lub vojvoog loj ntawm 5 units thiab lub vojvoog me ntawm 3 units, thaj tsam ntawm lub ellipse yog 3 x 5 x π, lossis txog 47 square units.
