AND from below. At every iteration, the two perimeters are the same.
- wat10000 2y agoWhat two perimeters? There’s only one. And it hasn’t been shown to bound the triangle’s perimeter from below. It is plainly greater than the triangle’s perimeter at every step, so it just establishes an upper bound. To derive the triangle’s perimeter, you also need another thing that’s always less than the triangle’s perimeter, then show that the lower and upper bounds converge on the same value.
