Question

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

Answer 1

YES

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!

Yes, it is shown horizontal for both lines and they will never touch, therefore parallel.
