In the given figure, AB|\|CD|\|EF given that AB=7.5 cm, DC=y cm, EF=4.5 cm, BC=x cm. Find the values of x and y.
In /_\ABC , D, E, F are the mid-points of bar(AB) , bar(BC) , bar(CA) and if bar(AB) = 11 cm, bar(BC) = 9 cm, bar(CA) = 8cm. Find the lengths of bar(DE) , bar(EF) and bar(DF) .
In DeltaABC AC=12 cm , AB=5 cm and angleBAC=30^@ , then area of the DeltaABC is……………
In the adjacent figure DeltaABC and DeltaDBC are two triangles such that bar(AB) = bar(BD) and bar(AC) = bar(CD) . Show that DeltaABC ~= DeltaDBC.
If the position vectors of the points A,B,C are -2bar(i)+bar(j)-bar(k), -4bar(i)+2bar(j)+2bar(k), 6bar(i)-3bar(j)-13bar(k) respectively and bar(AB) = lambda bar(AC) then find the value of lambda .
