Help plz

k so im doing this assignment that if u enter the coordinates of a shape it displays it filled in with "*", i just cant figure out how to do that. I made a program that displays the triangle with equal size sides, but cant do it when random sides are put in, so far i have:

    	}
	}
	while(!quit);
	cin.ignore();
	cin.get();
	return 0;
}

so i only have the sides done dont know how to do the hypotenuse
----
so when u put in
5 6
11 6
5 15
it should output something like
*
**
***
*****
