# Distancia entre dos puntos

La distancia entre dos puntos, A y B, se puede calcular utilizando el Teorema de Pitágoras, como muestra la siguiente figura:

De donde concluimos que la distancia entre dos puntos A=(x1,y1) y B=(x2,y2) viene dada por la fórmula:

Calcula la distancia entre A=(-2,5) y B=(6,12).

Calcula la distancia entre los puntos A=(4,-7) y B=(4,-4)
