How do I prove that it is possible to cover the whole plane with squares with side 1?

Please suggest different approaches to the above problem.

Thank you.

    In English, statements such as "Suggest different approaches" can read as orders, or at least as somewhat rude. The polite way is to ask as question. E.g., "Could someone suggest an approach to the problem above?"2011-11-26
