Question

Which statement must be true to prove that segment DE is parallel to segment CA?

4 : EA = 1 : DC

2 : DC = 5 : EA

3 : EA = 2 : DC

1 : DC = 2 : EA

Answer 1

i think if the triangle BDE and BCA are similar so DE parallel CA is that right?

Answer 2

okay . TY (:

Answer 3

but by using the similarity laws i got 3DC=2EA

Answer 4

4 : EA = 1 : DC

2 : DC = 5 : EA

3 : EA = 2 : DC

1 : DC = 2 : EA

Answer 5

oh i thought the left numbers 4,3,2,1 is an inversed order not a part of the ratio and i did not see it is 4,2,3,1

Answer 6

by the way answer is C .....3:EA=2:DC
