is line de parallel to line bc, explain/ show how you know:

Answer:
YES
Step-by-step explanation:
Becasue the ratio of the length of the sides 6/9 is equivalent to the ratio of of the length of the sides 4/6:
6/9 = 4/6
If you simplify these you can see that they are of the same ratio, so the lines DE and BC must be parallel.
Hope this helps!
