Question

Determine o ponto médio do segmento AB em cada item:
a) A (2,3) e B (10,3) c) A (1,8) e B (5,2)
b) A (2,1) e B (6,7) d) A (3,1) e B (3,11)

Answer 1

As coordenadas do ponto médio são dadas por: M ( Xa + Xb / 2 ,   Ya + Yb / 2 ), assim, temos:

a) Xm = 2 + 10 / 2

Xm = 12 / 2

Xm = 6

Ym = 3 + 3 / 2

Ym = 6 / 2

Ym / 3

M ( 6, 3 )

b) Xm = 2 + 6 / 2

Xm = 8 / 2

Xm = 4

Ym = 1 + 7 / 2

Ym = 8 / 2

Ym = 4

M ( 4, 4 )

c) Xm = 1 + 5 / 2

Xm = 6 / 2

Xm = 3

Ym = 8 + 2 / 2

Ym = 10 / 2

Ym = 5

M ( 3, 5 )

d) Xm = 3 + 3 / 2

Xm = 6 / 2

Xm = 3

Ym = 1 + 11 / 2

Ym = 12 / 2

Ym = 6

M ( 3, 6 )
