Question
Find the centroid of the triangle whose vertices are (−5, −5), (1, −4) and (−4, −2)
Solution
Let the vertices of a triangle be A(−5, −5), (1, −4) and C(−4, −2)
Centroid of a ΔG = `((x_1 + x_2 + x_3)/3, (y_1 + y_2 + y_3)/3)`
= `((-5 + 1 - 4)/3, (-5 - 4 - 2)/3)`
= `((-8)/3, (-11)/3)`
Centroid is `((-8)/3, (-11)/3)`
