If the point A (-1, 3), B(1,-1) and ( (5, 1) are the

veselices of a AABC. Find the length of the median

through the vertex d. also find the coordinate of the

controid of this triangle

veselices of a AABC. Find the length of the median

through the vert

By Adeline

Answer:come ordinates of median AD from vertex a on BC is

x co ordinate = 1+5/2 =6/2 =3

y co ordinate -1+1/2=0

length of median AD =[(-1+3)^2 +(3-0)^2]^1/2 = 5

coordinate of centroid of triangle ABC are

x coordinate =-1+1+5 /3 =5/3

y coordinate = 3+(-1) +1 /3 =3/3= 1
