Square:
>> All the four sides are congruent.

Rectangle:
>> The opposite sides are congruent (not all the four sides)

I think that's the only difference about them. 

And we can conclude that square can be a rectangle but a rectangle could never be a square. ☺

Their opposite side is parallel and congruent. Opposite angles are congruent. Consecutive angles are supplementary. However, in rectangle its diagonals bisect each other, congruent, and separate the parallelogram to 2 congruent angles. Whereas, square is perpendicular to its two diagonals.
