Answer:
The proposition is true, as
and
satisfies the given expression (
).
Step-by-step explanation:
Vertices of the triangle ABC are located in
,
and
, respectively. By definition of midpoint, we get that M and N are located in the following coordinates:
(Eq. 1)



(Eq. 2)



Then, the relative vectors between A and C, as well as M and N are, respectively:
(Eq. 3)


(Eq. 4)


By getting back into (Eq. 3), we find the following the result after some algebraic handling:
