If the point A (-1, 3), B(1,-1) and ( (5, 1) are theveselices of a AABC. Find the length of the medianthrough the vertex d. also find the coordinate of thecontroid of this triangle About the author 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 Reply
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
