# C# Sharp Exercises: Check whether a triangle can be formed by given value

## C# Sharp Conditional Statement: Exercise-15 with Solution

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

Sample Solution:-

C# Sharp Code:

``````using System;
public class Exercise15
{
public static void Main()
{
int anga, angb, angc, sum; //are three angles of a triangle
Console.Write("\n\n");
Console.Write("Check whether a triangle can be formed by given value:\n");
Console.Write("--------------------------------------------------------");
Console.Write("\n\n");

Console.Write("Input angle1 of triangle: ");

Console.Write("Input angle 2 of triangle: ");

Console.Write("Input angle 3 of triangle: ");

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

/* Check whether sum=180 then its a valid triangle otherwise not */
if(sum == 180)
{
Console.Write("The triangle is valid.\n");
}
else
{
Console.Write("The triangle is not valid.\n");
}
}

}
```
```

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.
```
