Is a square a rectangle? Yes.
Is a square is a parallelogram. Yes.
Is a square is a quadrilateral. Yes.
Is any rectangle a square? No.
Are a square and a rectangle the same thing? No.

Think general versus specific categories. A Ford is a car. Not
all cars are Fords. A squares is a rectangle. A rectangle
is a parallelogram. A parallelogram is a quadrilateral.
Each category is more general, including the previously named
category, plus more.
