As you can see the number of spaces decreases with each row while we move towards the base of the triangle, so this loop runs one time less with each iteration. You may be happy to settle for a "close enough" approach like Chris Jester-Young's. 3) The outer loop executes the total code until condition false. The right triangle perimeter is the sum of the measures of all the 3 sides. If your method isRight() is supposed to to compute the answer from 3 floating point values, it will never work, because as others have pointed out you will get inaccuracies in your calculations.
