Question

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

Answer 1

#include <stdio.h>

void main()  

{  

   int anga, angb, angc, sum; //are three angles of a triangle  

 

   printf("Input three angles of triangle : ");  

   scanf("%d %d %d", &anga, &angb, &angc);  

 

   /* 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)    

   {  

       printf("The triangle is valid.\n");  

   }  

   else  

   {  

       printf("The triangle is not valid.\n");  

   }  

}
