#include <iostream>

int main()
{
   std::cout << "Enter the lengths of three sides of a triangle:";
   float a, b, c;
   std::cin >> a >> b >> c;

   if ((a * a == b * b + c * c) || (b * b == a * a + c * c) || (c * c == a * a + b * b))
     std::cout << "The triangle is a right triangle" << std::endl;
   else
     std::cout << "The triangle is not a right triangle" << std::endl;
}
