Answer 3

thnx, its in the document

Answer 4

It is so simple...

What you have to Do is to find the Distance CD and AD and if it becomes equal then it is proves that the lines are parallel...

Answer 5

ohh ok

Answer 6

1st qeustion is
As we can see, point A is (0,0) therefore any division would give 0, this makes it clear that we are using point c and point a, and finding the midpoint using the midpoint theorem. Hence we would get (x1 + 0)/2 and (y1+0)/2, which is naturally in correspondance to the point A (0,0)
If we look at point y, midpoint theorem is used again, as this time, B (x2, 0) and C (x1,y1) therefore the midpoint theorem is used again to get (x1+x2/2) , (y1/2) which is again in correspondance to the point B. Therefore we can conclude that the line segment BA is parallel to DE
