Write a C# Sharp program to check whether a triangle can be formed by the given angles value.

Sample Solution:-

C# Sharp Code:

using System;  // Importing the System namespace

public class Exercise15  // Declaration of the Exercise15 class
{  
    public static void Main()  // Entry point of the program
    {  
        int anga, angb, angc, sum;  // Declaration of variables to store three angles of a triangle and their sum
        Console.Write("\n\n");  // Printing new lines
        Console.Write("Check whether a triangle can be formed by given value:\n");  // Displaying the purpose of the program
        Console.Write("--------------------------------------------------------");  // Displaying a separator
        Console.Write("\n\n");

        // Prompting user to input three angles of a triangle
        Console.Write("Input angle1 of triangle: ");
        anga = Convert.ToInt32(Console.ReadLine());

        Console.Write("Input angle 2 of triangle: ");
        angb = Convert.ToInt32(Console.ReadLine());

        Console.Write("Input angle 3 of triangle: ");
        angc = Convert.ToInt32(Console.ReadLine());

        /* Calculate the sum of all angles of the triangle */
        sum = anga + angb + angc;  // Summing up the three angles

        /* Check whether the sum is equal to 180 degrees to determine if it's a valid triangle */
        if(sum == 180)   
        {  
            Console.Write("The triangle is valid.\n");  // Printing a message if the triangle is valid
        }  
        else  
        {  
            Console.Write("The triangle is not valid.\n");  // Printing a message if the triangle is not valid
        }  
    }
}

Sample Output:

Check whether a triangle can be formed by given value:                                                        
--------------------------------------------------------                                                                                          
Input angle1 of triangle: 90                                                                                  
Input angle 2 of triangle: 45                                                                                 
Input angle 3 of triangle: 45                                                                                 
The triangle is valid.
