A, B, C and D,E,F are sets of points on two parallel lines L1 and L2 respectively. AF, BE, and CD intersect at 0.

prove AB/EF = AC/DF = BC/DE

this is after naming the 3 pairs of similar triangles.

if anyone can show how to prove it i will be very grateful. :D

try drawing the diagram and then simply connecting the points quoted.

the three similar triangles are:

ABO&FEO, CBO&DEO and AOC&FOD

i know they are similar but how to prove that the ratio for all triangles are equal.
