Question

In a triangle ABC , DE||BC , AB/BC=2 THEN FIND DE/BC

Answer 1

Answer:

Step-by-step explanation:

I assume that the points D and E lie on the sides AB and AC respectively.

In that case it is easy to see that, ∆ABC and ∆ADE are similar(D=B and E=C and A is common between the triangles).

Similar triangles have their sides proportional ie., AD:AB = DE:BC = CA:EA.

Hence DE = BC / 2 = 3.
