Question

Determine as coordenadas dos pontos médios nos seguintes casos:
A) A (2,4) e B(4,8)
B) C(6,10) e D(4-6)
C) D(-2,-1/3) e E(-6,3/4)

Answer 1

a) Xm = Xa + Xb / 2
Xm = 2+4/2 = 6/2 = 3

Ym = Ya+Yb / 2
Ym = 4+8/2 = 12/2 = 6    M(3,6)


b) Xm = 6+4/2 = 10/2 = 5

Ym = 10+(-6) /2 = 10-6/2 = 4/2 = 2    M(5,2)


c) Xm = -2+(-6) / 2 = -2-6/2 = -8/2 = -4

Ym = -1/3 + 3/4 / 2 = -4/12 + 9/12 / 2 = 5/12 / 2 = 5/12 * 1/2 = 5/24    M(-4, 5/24)
