Question

Considere os pontos A(-3,-1), B(0,2) e C(5,-7). Calcule as coordenadas do baricentro do triângulo , cujos vértices são os pontos A, B e C.

Answer 1

A(-3,-1)
B(0,2)
C(5,-7)

XG = ( xa + xb + xc ) / 3

XG = ( -3 + 0 + 5 ) / 3

XG = 2/3

YG = ( ya + yb + yc ) / 3

YG = ( -1 + 2 - 7 ) / 3

YG = -6/3

YG = -2

G(2/3,-2)
