To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. 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. * Lecture1 / RightTriangle.java Go to file Go to file T; Go to line L; Copy path . This means that the threshold in the close enough thing doesn't need to be that small for it to work. The outer loop is used to run for the number of rows given as input. * If the Right Triangle is Isosceles, the two sides of the same length are opposite the wrong angles to the Right Triangle.
