1. Define an enumeration type, named triangleType, that has the values scalene, isosceles, equilateral, and no Triangle (20 points) 2. Write a function triangle Shape, that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle (enum) (Note In a triangle, the sum of the lengths of any two sides is greater than the length of the third side) (40 points) 3. In the main function prompts the user to input the length of the sides of the triangle and outputs the shape of the triangle (20 points) 4 In the main function, use returned enum data type (from the triangle Shape function) in the switch statement to display the type of a triangle to the user (20 points) Ext: If the input is 456 Output: Your triangle is: scalano Ex2 If the input is. 10 5 50 Output this ie non a triangle
