Question

Ache as coordenadas de P, ponto médio do segmento ⁻AB⁻, nos casos abaixo:

a) A(1, 3) e B(14, -6)

b) A(-4, 0) e B (1/2, 1)

c) A(-3/4, 1/2) e B(2/3, -1/3)

Answer 1

(A)

xp = (1+14)/2 = 15/2

yp = (3-6)/2 = -3/2

P ( 15/2 , -3/2 )

(B)

xp = (-4+1/2)/2 = (-8/2+1/2)/2 = -7/4

yp = (0+1)/2 = 1/2

P ( -7/4 , 1/2 )

(C)

xp = (-3/4+2/3)/2 = (-1/12)/2 = -1/24

yp = (1/2-1/3)/2 = (1/6)/2 = 1/12

P ( -1/24 , 1/12 )
