Question

Find the centroid of the triangle whose vertices are ( 17, -8), ( -9, 17) and (8, 13)

Answer 1

Answer:

Step-by-step explanation:

IF YOU HAVE THE CO-ORDINATES OF THE VERTICES GIVEN:-

(Remember that the centroid divides the median in the ratio 2:1)

1. Using midpoint formula, find the midpoint (let's call it M) of the side opposite to your chosen vertex (let's call it A).

2. Using section formula, find the co-ordinates of the centroid (let's call it G)  

(Remember A-G-M)

3. Using distance formula, find out the distance between A and G.
