#Write a function hypotenuse that has two parameters, sides of right 
#triangles, and returns the length of hypotenuse using the following 
#formula: hypotenuse=sqrt(a^2+b^2), where a and b are other sides of right 
#triangle 
#Write a program that reads sides of THREE triangles, finds the length of 
#hypotenuse for each and the triangle with the longest hypotenuse. Use 
#function sqrt from math library. Don't forget to have import math 
#statement in your program. To use function from math library use 
#math.sqrt syntax
