(PYTHON) Write a program that prompts user to enter three sides of a triangle. The program should determine if the three sides can form a triangle. If the three sides can form a triangle, then determine the type of the triangle. There are three types of triangles: Equilateral triangle (all 3 sides are equal) Isosceles triangle (two sides are equal, the third side is of a different length) Right triangle (the square of the length of the longest side is equal to the sum of the squares of the lengths of the other two sides)
