#include <iostream>

using namespace std;

int main() {
	int x, y, z;
	int sum = 0;

	cin >> x >> y >> z;

	sum = x + y + z;
	
	if (sum == 180) {
		if (x == 60 && y == 60 && z == 60) 
			cout << "Equilateral";
		else if (x == y || x == z || y == z)
			cout << "Isosceles";
		else
			cout << "Scalene";
	}
	else
		cout << "Error";

	return 0;
