Pictorial Presentation:

Sample Solution:
C Code:
#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");
}
}
