 Geometría Distancia entre dos rectas Si las rectas r y s son coincidentes o secantes, d(r,s) = 0 Si las rectas r y s son paralelas, sus ecuaciones son de la forma r: ax+by+c=0 y s: ax+by+c'=0 y se cumple que: $\fs3\;d(r,s)\;=\;\frac{|c^\prime\;-\;c\;|}{sqrt{a^2+b^2}}$ Calcula la distancia entre las rectas r: 3x+4y-8=0 y s: 6x+8y+4=0 d(r,s) =
