In the given `DeltaABC`, points D and E are mid points of AB and AC and also BC=6 cm then find DE.

In DeltaABC , D, E and F are the mid points of the sides, then DeltaDEF =

In the figure, D,E are mid-points of AB and AC then triangle ADE : square BCED =

In a Delta ABC , if D is the mid point of BC and AD is perpendicular to AC , then cos B =

In the figure, D,E are mid-points of AB and AC then DeltaADE:squareBCED =

In DeltaABC ,BC=8cm and D, E are the midpoints of AB and AC, also AF=1/2 AD and AG=1/2 AE , then FG=

In the figure, D and E are the points on sides AB and AC of triangle ABC such that DE || B C. " if "angle B = 30^(@) and angle A = 40^(@), find (i) x (ii) y (iii) z

In DeltaABC , P, Q and R are mid points of the sides AB, BC, and CA respectively. If D is any point i) then express bar(DA)+bar(DB)+bar(DC) in terms of bar(DP), bar(DQ) and bar(DR) ii) If bar(PA)+bar(QB)+bar(RC)=bar(a) then find bar(a) .

In the figure, D and E are the points on sides AB and AC of /_\ABC such that DE|\|BC. and divides △ABC into two parts, equal in area, Find AB BD ​ .

In the figure D,E are the midpoints of the sides AB and AC. IF DE=4cm, then BC=
