    So the interval AB is the hypotenuse of the right angled triangle with other sides of 2, and 3 pythag says 2^2 + 3^3 = AB^2 ie AB = √ ( 2^2 + 3^3 ) =

    simplify AB, what do you get? we still need to find BC and CA

    Ok, so your saying do 2^2 + 3^3= 13?

    Whoops, some typos: pythag says 2^2 + 3^2 = AB^2 ie AB = √ ( 2^2 + 3^2 ) = √ 13 (some how you got the thirteen right)
