Answer 15

To prove that DE is parallel with AB we need to prove that D is the midpoint of AC and prove that E is the midpoint of BC. We see that D is half of (x1, y1). (x1,y1) is where C sits. So through substitution D is half the distance from the origin compared to C. because A is at the origin, D is the midpoint of AC. Now to prove E is the midpoint of BC. E is at ((x1+x2) /2, y1 /2). When finding the difference in distances between B and E you are left with half of (x1, y1), meaning it is half of C. meaning that the other half has to belong to B, therefore explaining that E is in the middle. and by the midpoint theorem which states that a line running through the midpoint of to sides of a triangle will be parallel with the third side.
