Question

1 ) Calcule o baricentro.
A (4,-3) b(7,2) c (8,1)
A (5,-4 ) b(0,7) c (10,2)

2) calcule o ponto médio
A(4,3) b (-1,-2)
A (10,-2) b (3,5)

Answer 1

1)
G(4+7+8/3 , -3+2+1/3) => G(19/3 , 0)
G(5+0+10/3 , -4+7+2/3) => G(5 , 5/3)

2)
M(4-1/2 , 3-2/2) => M(3/2 , 1/2)
M(10+3/2 , -2+5/2) => M(13/2 , 3/2)
