Question

dados os pontos a(2,6) b(4,2) e c(-2,4) calcule o ponto medio ab,ac e bc

Answer 1

$M_{ab} = (( \frac{ x_{a} + x_{b} }{2} ),( \frac{ y_{a} + y_{b} }{2} )) = (( \frac{2+4}{2} ),( \frac{6+2}{2} ))= (3,4)$

$M_{ac} = (( \frac{ x_{a} + x_{c} }{2} ),( \frac{ y_{a} + y_{c} }{2} )) = (( \frac{2+(-2)}{2} ),( \frac{6+4}{2} ))= (0,5)$

$M_{bc} = (( \frac{ x_{b} + x_{c} }{2} ),( \frac{ y_{b} + y_{c} }{2} )) = (( \frac{4+(-2)}{2} ),( \frac{2+4}{2} ))= (1,3)$
