Question

2-) Determine o Baricentro dos Triângulos de Vértices :
a-) A( 2, 5) ,B( 4, 6) e C ( 9, 4)
b-) A( 0, 7) , B ( 2, -5 ) e C (13, 13)

​

Answer 1

a. G = (5, 5)

$XG = \frac{2 + 4 + 9}{3} = \frac{15}{3} = 5$

$YG = \frac{5 + 6 + 4}{3} = \frac{15}{3} = 5$

b. G = (5, 5)

$XG = \frac{0 + 2 + 13}{3} = \frac{15}{3} = 5$

$YG = \frac{7 + ( - 5) + 13}{3} = \frac{ 2 + 13}{3} = \frac{15}{3} = 5$
