|Interactive Mathematics Miscellany and Puzzles, Alexander Bogomolny|
|Division of a square by evenly spaced lines parallel to its sides yields a number of small squares which is clearly square. Interestingly, the same is true for a triangle divided by evenly spaced lines parallel to its sides. The page contains a dynamic illustration of this result and a demonstration that it is equivalent to the well known fact that the sum of a series of odd numbers is a square.|
