Answer 1

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

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.
