Question

The coordinates of the centroid of a triangle whose vertices are (-1, 7), (8,13) and (8, 1) is​

Answer 1

The formula for centroid of a triangle is

$\frac{x1 + x2 + x3}{3} \: and \: \frac{y1 + y2 + y3}{3}$

applying in formula ,

$\frac{ - 1 + 8 + 8}{3} and \: \frac{7 + 13 + 1}{3}$

$\frac{15}{3} and \frac{21}{3}$

Hence the coordinates are (5,7) .
