Question

find the length of the medians of the triangle whose vertices are (-1,3), (1,-1) and (5,1).

Answer 1

the question is not clear,

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!

Answer 2

Step-by-step explanation:

D=(1+5)/2 , (-1+1)/2

=(6/2, 0/2 )

(3,0)

• By distance formula = (-1-3)2+ (3-0)2
• =( -4)2+( 3)2
• = √ 16+9
• =√25
• = 5
