Construct a quadrilateral ABCD, given that AB = 4.5 cm, BC =5.2 cm,CD = 4.8 cm and diagonals AC= 5 cm and BD = 5.4 cm.
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 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 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 A,B, C and D are four points, then show that |bar(AB) xx bar(CD) + bar(BC) xx bar(AD) + bar(CA) xx bar(BD)| is four times the area of Delta ABC
In the given figure three lines bar(AB) , bar(CD) and bar(EF) intersecting at O. Find the values of x, y and z it is being given that x : y : z = 2 : 3 : 5
If A = (1,-1,0), B=(1,2,1), C=(2,3,0) and D=(0,1,t). Be four points. If the projection of bar(AB) " on " bar(CD)" is equal to that of " bar(CD) " on " bar(AB) , then find t.
