Question

Which statement must be true to prove that segment DE is parallel to segment CA?
Answer
2 : DC = 5 : EA
3 : EA = 2 : DC
1 : DC = 2 : EA
4 : EA = 1 : DC

Answer 1

I'd like for the angles E and A to be congruent. Also angles C and D. That would make those two triangles similar. So, similar triangles is what you're aiming for.
Similar triangles have proportional sides.

Answer 2

so it would be the first one :)
