Hey can anyone me!

in δabc shown below, segment de is parallel to segment ac:

triangles abc and dbe where de is parallel to ac

the two-column proof with missing statements and reasons proves that if a line parallel to one side of a triangle also intersects the other two sides, the line divides the sides proportionally:

statement reason
1. line segment de is parallel to line segment ac 1. given
2. line segment ab is a transversal that intersects two parallel lines. 2. conclusion from statement 1.
3. 3.
4. ∠b ≅ ∠b 4. reflexive property of equality
5. 5.
6. bd over ba
