Question

find the centroid of a triangle,whose vertices are (1,-1),(-4,6) & (-3,-5).​

Answer 1

Answer:

The centroid is the intersection of all the medians of a triangle.

Step-by-step explanation:

(x,y)={(x1+x2+x3)/3, (y1+y2+y3)/3}

= {(1+-4+-3)/3 , (-1+6+-5)/3}

= {(-7+1)/3 , (-6+6)/3}

= {-6/3, 0/3}

= {-2, 0}

Answer 2

Answer:(-2,4/3)

Step-by-step explanation:

here, (1,-1)=(x1,y1)

        (-4,6)=(x2,y2)

         (-3,-5)=(x3,y3)

now,

centroid=[(x1+x2+x3)/3],[(y1+y2+y3)/3]

             =(-2,0)
