just abcd Actually, it is the first four letters of the alphabet. in geometry?
Yes.... -_-l!ii
abCD
Because - for example - if you search for abcd*.* - the file system will search for any file beginning with the letters abcd. If you search for abcd*.txt - the system will find only files beginning abcd and having the extension .txt

In parallelogram ABCD, AC=BD. Is ABCD a rectangle?
dcba = 9 x abcd dcba/9 = abcd Since the quotient is also a 4 digit number, then d in order to be divided by 9, must be the biggest digit which is 9. So that d = 9 and a = 1. The same way for other digits... So that we have: dcba = 9 x abcd 9999 = 9 x 1111
