Best ResponseYou've already chosen the best response.0well the corresponding sides in the triangles are triangle ABC and triangle ACD are AB AC AB DC BC AD now you need to use the ratio's of corresponding sides in similar triangles

Best ResponseYou've already chosen the best response.0but ques. does'nt say that it divides the triangles in equal areas!

Best ResponseYou've already chosen the best response.0SIMILARITY CAN ONLY BE USED WHEN AREAS ARE EQUAL

Best ResponseYou've already chosen the best response.0oops corresponding side should be AC and DC so using the ratio of corresponding sides \[\frac{4}{9} = \frac{AB}{AC}= \frac{AC}{ DC}\]

Best ResponseYou've already chosen the best response.0who knows.... it doesn't make sense to me... there seems to be something missing from the question.

Best ResponseYou've already chosen the best response.0Oh, and triangles can be similar and have different areas the ratio will be the linear ratio squared. so the ratio of areas in the triangles is ABC:ACD = (4/9)^2
