    Well you can always try the pythagorean theorem.. and take the two shortest sides and do sqrt(x^2 +y^2) and you will get the 3rd side

    if the 2 shorts equal the long, its a straight line; if the two shorts are less than the long, you aint got nothing,

    oops amistre you are right about the 1 1 2. sorry forgot to take square root of 2 which is not equal to 2 so the first is not a triangle.
