Algorithm to Check Triangle is Valid or Not using Angles

Follow the below given algorithm to write a program to find the third angle of a triangle if two angles are given; as follows:

  1. Take input angles of triangle from user and store it in some variables.
  2. Compute sum of all three angles, store sum in some variables.
  3. Check if(sum == 180) then, triangle can be formed otherwise not.

C Program to Check Triangle is Valid or Not using Angles

/* C Program to Check Triangle is Valid or Not using Angles */
 
#include<stdio.h>
 
int main()
{
	int angle1, angle2, angle3, Sum;
 
  	printf("\n Please Enter Three Angles of a Triangle : ");
  	scanf("%d%d%d", &angle1, &angle2, &angle3);
  	
  	Sum = angle1 + angle2 + angle3;
  	
  	if(Sum == 180)
  	{
  		printf("\n This is a Valid Triangle");
 	}
	else
	{
		printf("\n This is an Invalid Triangle");
	}  
 	return 0;
 }

The output of the above c program; as follows:

Please Enter Three Angles of a Triangle : 90 45 45
This is a Valid Triangle
