Expert Answer:
Let (x,y) and (X,Y) be the other two vertices.
Since (-2,3) is a midpoint of (1,1) and (x,y), using section formula,
-2 = (x+1)/2 and 3 = (y+1)/2
x = -5 and y = 5,
Similarly, (5,2) is the midpoint of (1,1) and (X,Y),
5 = (X+1)/2 and 2 = (Y+1)/2
X = 9 and Y = 3,
Two other two vertices are (-5,5) and (9,3).
