<prompt> Acha pointi A 0 ,0 ,0, B 1, 0, 0, C 0, 2, 0, na D 0, 0, 3 . Alama E, F, G, na H ni sehemu za kati za sehemu za mstari overlineBD, overlineAB, overline AC, na overline DC mtawalia. Tafuta eneo la quadrilateral EFGH.  <response>: Kwa kuwa E ndio kitovu cha overlineBD, na F ndio kitovu cha overlineAB, overlineEF ni sambamba na overlineAD, na EF fracAD2. Vile vile, overlineGH ni sambamba na overlineAD, na GH fracAD2. Tangu AD 3, EF GH frac32.asyukubwa wa kitengo 1 cm;jozi A, B, C, D, E, F, G, H;A 0,0;B 3,0;C 2dir220;D 0,3;E B D2;F A B2;G A C2;H C D2;choraA--B,iliyopigwa;kuchoraA--C,dashed;kuchoraA--D,dashed;kuchoraB--C--D--mzunguko;kuchoraE--F--G--H--mzunguko;leboA, A, NE;leboB, B, dir0;leboC, C, SW;leboD, D, N;leboE, E, NE;leboF, F, NE;leboG, G, W;leboH, H, W;asyVilevile, overlineFG na overlineEH ni sambamba na overlineBC, na FG EH fracBC2 fracsqrt5 2. Kwa kuwa overlineAD na overlineBC ni perpendicular, EFGH ni mstatili. Kwa hiyo,EFGH frac32 cdot fracsqrt52 frac3 sqrt54.
