Respuesta :
measure with a metric ruler if straight line is curved use string. then measure length of string.
if you have the points
(x₁,y₁) and (x₂,y₂)
the distance between them is
distance=[tex] \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} [/tex]
(x₁,y₁) and (x₂,y₂)
the distance between them is
distance=[tex] \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} [/tex]
