WE CAN APPLY MID POINT FORMULA.
THEN SOLVE

Let the coordinates of the midpoint be D,E,F for the sides a,b,c respectively

Coordinates of D+coordinates of E - coordinates of F gives u the coordinates of the vertex opposite to F , i.e, C

lly
Coordinates of E+coordinates of F - coordinates of D gives u the coordinates of the vertex opposite to D i.e, A
