Expert Answer

Let A(x1,y1),B(x2,y2) and C(x3,y3) are the vertices of the triangle

points (10, 5) , (8, 4) and (6, 6) are the mid-points of the sides of a triangle

x1+x2=20  i.e x2= 20-x1

x2+x3=16  i.e 20-x1+x3=16 or 4 =x1-x3---A

x1+x3=12 ----B
Solving Aand B

2x1 =16, x1  =8

 x3=4, x2=12

Similarly Solve these toget y coordinates

y1+y2=10 y2+y3=16 andy3+y1=12
