WebProcedure to develop method to find square root value 1) Take a iterator variable and initialize it with 1. 2) Check the given number is perfect square? If i*i = n then i is the square root value of n. 3) Else find the smallest value of i for whcih i*i is strictly greater than n. The square root lies in the interval i-1 to i. 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.
