Determine as coordenadas a seguir no ponto médio.

a) A (3,4) e B (5,6) M ( x, y)
b) B (1,5) M (5,3) A (x,y)
c) A (3,1) M ( 2, 4) B (x,y)

Answer 1

Resposta:

Explicação passo-a-passo:

(3,4)+(5,6)/2= (4,5)

(1,5)+(x,y)/2= (5,3)

(1+x, y+5)=(5,3) x 2

(1+x, y+5)= (10, 6)

1+x=10

x=10-1= 9

y+5=6

y=6-5=1

(3,1)+(x,y)/2= (2,4)

(3+x, 1+y)=(2,4) x 2

(3+X,1+y)= (4,8)

3+x=4

x=4-3= 1

1+y=8

y=8-1

y=7
