Square is a subset of rectangle, so all squares are rectangles. However, not all rectangles are squares. Rectangle can have incongruent adjacent sides, but square must have congruent adjacent sides.

Quadrangles are all four figured shapes including regular (with names like square and parralelogram) and irregular with all different length sides. (satguru)

All squares are rectangles. A rectangle has four right angles. However, not all rectangles are squares. A square does have four right angles, but the sides must also have the same measurement. So, only some rectangles are squares.
