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 figure 11.34, ABCD is a quadrilateral in which bar(AB) = bar(AD) and bar(BC) =bar(DC). Diagonals bar(AC) and BD intersect each other at O.Show that-

ABCDE is a regular hexagon. i) If bar(AB) + bar(AE)+ bar(BC) + bar(DC) + bar(ED) + bar(AC)=lambdabar(AC) then lambda=

If ABCDE is a pentagon, then bar(AB) + bar(AE) + bar(BC) + bar(DC) + bar(ED) =
