Do you need to find the distance between all three possible pairings? The formula for the distance between two points (X1, Y1) and (X2, Y2) is d = sqrt((X2 - X1)^2 + (Y2 - Y1)^2).

Taking (4, 2) and (3, -1) as an example, you get d = sqrt((3 - 4)^2 + (-1 - 2)^2) = sqrt((-1)^2 + (-3)^2) = sqrt(1 + 9) = sqrt(10).
