For a start, a square IS a rectangle, so it has ALL the properties of a rectangle. A square has the additional property that all of its sides have the same length.
Similitude : Le rectangle et le parallélogramme ont quatre cotés parallèles deux à deux Différence : seul le rectangle a quatre angles droits (90°)
Depends on the type of piano I guess. Most keyboards are rectangle shaped, there are rectangle/square shaped grand pianos but they are not common, most uprights are rectangle.
never - the only thing it may have is common is that a simple rectangle will have four right angles. But a rectangle is not simple, it is complex.
They are all polygons

The similarities are rectangle is shape like L and the other 1 I sharp as an equal
They are all polygons.
Quadrilateral
No they do not.

They are both polygons.
They are both quadrilaterals.

all quadrolaterants
