Since it is a right triangle Pythagoras theorem gives you a second equation in a, b and c. The third equation you use depends on what you know about a 306090 triangle. I know that the length of the hypotenuse is twice the length of the shortest side so that will give a third equation. Solve the three equations for a, b and c and make sure you verify that the perimeter is 6. Penny
