Web1 aug. 2013 · If your check passes for two points, it's definitely a square. Alternative: You can check if it's not a square. In a valid square, there are only two valid distances, side length ( s ), and diagonal length ( d ). Since you're using squared distance, d = s * 2 If any distance (there are only six) does not equal either d or s, it cannot be a square. WebFor example, 4, 9, and 16 are all perfect squares because they can be written as 2 * 2, 3 * 3, and 4 * 4, respectively. To determine if a number is a perfect square, you can take the square root of the number and see if it is an integer. For example, the square root of 4 is 2, which is an integer, so 4 is a perfect square.
