i have to show that if the midpoints of consecutive sides of any quadrilateral are connected the result is a parallelogram.
i know the answer but do not know how to get it, help with explaining the process would be appreciated.
I think the midpoints are right but i am not sure, i got them myself.
Midpoint of line A:
Midpoint of line B:
Midpoint of line C:
Midpoint of line D:
Here is where i get stuck, i do not know how to prove that the slopes of opposite sides are equal.
