so, i take A(-1, 3), B(1, -1), C(5, 1) and find the length of median through vertex C
In a triangle of ABC. Let the midpoint be D which lies in between B and C
So, D = (1+5/2, -1+1/2) = (3,0)
So, Length of median = root of [(-1-3)^2 + (3-0)^2]
= root of [(4)^2 + (3)^2]
= root [16 + 9]
= root 25
= 5
Hope this helps!
Step-by-step explanation:
D=(1+5)/2 , (-1+1)/2
=(6/2, 0/2 )
(3,0)
