**int main(){**

**int a,b,c;**

**cout<<"Input firstside: ";**

**cin>>a;**

**cout<<"Input secondside: ";**

**cin>>b;**

**cout<<"Input thirdside: ";**

**cin>>c;**

**if((a*a+b*b==c*c)||(a*a+c*c==b*b)||(c*c+b*b==a*a))**

**cout<<"Triangleis right"<<endl;**

**else**

**cout<<"Triangleis not right"<<endl;**

**return 0;**
