Question

1- Determine as coordenadas do ponto médio: a) A(5,-1); B(7,-9).

b) A(4,5); B(-8,-11).

c) A(-6,4); B(-4,8).

d) A(-1,5); B(-9,-15)​.​ ​

Answer 1

Resposta:

Explicação passo a passo:

a

xm=5+7/2=12/2=6

ym=-1-9/2=-10/2=-5

M(6,-5)

b

xm=4-8/2=-4/2=-2

ym=5-11/2=-6/2=-3

M(-2,-3)

c

xm=-6-4/2=-10/2=-5

ym=4+8/2=12/2=6

M(-5,6)

d

xm=-1-9/2=-10/2=-5

ym=5-15/2=-10/2=-5

M(-5,-5)
