Question

determine as coordenadas do baricentro de um triangulo ABC considerando A(7,-4), B(-1,8) e c(3,-10)

Answer 1

As coordenadas do baricentro de um triângulo são dadas por:

$G=( \frac{x_A+x_B+x_C}{3} , \frac{y_A+y_B+y_C}{3} )$

Substituindo as coordenadas de A, B e C.

$G=( \frac{7-1+3}{3} , \frac{-4+8-10}{3} ) \\ G=( \frac{9}{3} , \frac{-6}{3} ) \\ G=( 3 , -2 )$
