Question

1) Calcule as coordenadas do ponto médio dos segmentos:

a) A(4,2) e B(6,4).

b)C(0,-4) e D(-6,-2)

Answer 1

a)
Xm = ( xA + xB ), (yA + yB) → Xm = ( 4 - 6), (2 - 4)  →
               2               2                            2         2
Xm = ( -2 ), (- 2) → Xm = (-1, -1)
            2        2 

b)
Xm = ( xA + xB ), (yA + yB) → Xm = ( 0 - (-6), (-4 - (-2)  →
                 2               2                           2             2
Xm = (0 + 6), (- 4 + 2) → Xm = ( 6 ), ( -2 ) → Xm = (3, -1)
              2           2                     2      2
