#include<iostream>
using namespace std;

int main()
{
 int angle1,angle2,angle3;
 cout<<"Enter the three angles of triangle:";
 cin>>angle1>>angle2>>angle3;

 if (angle1+angle2+angle3==180)
  cout<<"Triangle is valid";
 else
  cout<<"Triangle is not valid";

 
 return 0;
}

  The Output Is:  

SAMPLE RUN # 1

Enter the three angles of triangle:60 50 50
Triangle is not valid

SAMPLE RUN # 2

Enter the three angles of triangle:60 90 30
Triangle is valid
