#include <bits/stdc++.h>
using namespace std;
int main()
{
    int a, b, c, c1, sum;
    cin >> a >> b >> c;
    sum = a + b + c;
    a = min (a,min(b,c));
    c = max (a,max(b,c));
    b = sum - a - c;
    if (a + b <= c) 
    {
        cout << "Not triangle";
    }
    else
    {
        if ((a * a + b * b)  == c * c) cout << "Right triangle" << "\n";
        else if ((a * a + b * b)  > c * c) cout << "Acute triangle" << "\n";
        else if ((a * a + b * b)  < c * c) cout << "Obtuse triangle" << "\n";
        if (a == b || a == c || b == c) cout << "Isosceles triangle" << "\n";
        if (a == b && b == c) cout << "Equilateral triangle" << "\n";
    } 
    return 0;
}

帮忙看看吧
