```cpp
#include<iostream>
using namespace std;
int a,b,c;
int main()
{
cin>>a>>b>>c;
if(a+b<=c||b+c<=a||a+c<=b){
cout<<"Not triangle"<<endl;
return 0;
}
if(a*a+b*b>c*c&&b*b+c*c>a*a&&a*a+c*c>b*b)
cout<<"Acute triangle"<<endl;
if(a*a+b*b==c*c||b*b+c*c==a*a||a*a+c*c==b*b)
cout<<"Right triangle"<<endl;
if(a*a+b*b<c*c||b*b+c*c<a*a||a*a+c*c<b*b)
cout<<"Obtuse triangle"<<endl;
if(a==b||b==c||c==a)
cout<<"Isosceles triangle"<<endl;
if(a==b&&a==c)
cout<<"Equilateral triangle"<<endl;
return 0;
}
