1.) If a triangle has the sides of 21 and 24 the shortest it could be is 3.001. The smallest it could be is 3.001 because my theory is that for the shortest you have to subtract the smaller number from the bigger number and then add .001.
2.) If a triangle has the sides of 21 and 24 the longest it could be is 44.999. The longest it could be if 44.999 because in my theory the largest is found when you add the two numbers together and then subtract .001.
3.) It would not work because 50 is to big it needs to be a smaller number.
