Question

Find the co-ordinates of the point of intersection of the medians of the triangle formed by joining the points (-1, - 2), (8, 4) and (5, 7).​

Answer 1

Answer:

hope this helps

Step-by-step explanation:

A:-(-1,-2)

B:-(8,4)

C:-(5,7)

let D be the mid point of BC

coordinate of D by section formula

D=(13/2,11/2)

let G be the centroid

AG:GD=2:1

co-ordinate of point G

(used section formula)

x={2(13/2)-1}/3

x=4

y={2(11/2)-2}/3

y=3

so the co-ordinate of point G are (4,3)

Ans:- co-ordinates of the point of intersection of the medians of the triangle are (4,3)
