C Program to Check if Triangle is Valid or Not using Angles
Write a Program to Check if Triangle is Valid or Not using Angles
// C Program to Check if Triangle is Valid or Not using Angles
#include <stdio.h>
int main()
{
int angle1, angle2, angle3, total;
printf("Enter Angle 1 :--> ");
scanf("%d", &angle1);
printf("Enter Angle 2 :--> ");
scanf("%d", &angle2);
printf("Enter Angle 3 :--> ");
scanf("%d", &angle3);
total = angle1 + angle2 + angle3 ;
printf("\nSum of Angles :--> %d\n", total);
if( total == 180)
{
printf("Sum of angle is 180, so It is a Valid Triangle\n");
}
else
{
printf("Sum of Angle is not 180, so, It is an invalid Triangle");
}
return 0;
}
Output:
Run - 1:
Enter Angle 1 :--> 50
Enter Angle 2 :--> 60
Enter Angle 3 :--> 70
Sum of Angles :--> 180
Sum of angle is 180, so It is a Valid Triangle
Run - 2:
Enter Angle 1 :--> 40
Enter Angle 2 :--> 50
Enter Angle 3 :--> 60
Sum of Angles :--> 150
Sum of Angle is not 180, so, It is an invalid Triangle
