Question

Theorem 54=If a line divides two sides of a triangle proportionally, then it is parallel to the third side.

Please answer in a two-column proof-statements and reasons. **Also, it should have ONLY one given (statement).** I have an example of how it should look like/how it should be done in the second picture.

It is about lines proportional. The question is in the picture. *The question is completely clear, so please don't reject the question.*
